SC563 Dual Output 300mA LDO Linear Regulator POWER MANAGEMENT
Description
Features
The SC563 is a dual output, low dropout linear voltage regulator designed for use in battery powered applications and other applications with space constraints and low power requirements. The SC563 provides fixed output voltages up to 300mA of load current per channel. Fixed output voltages for each output eliminates the need for external feedback resistors.
Input voltage range — 2.3V to 5.5V Two 300mA (maximum) outputs Dropout at 300mA load — 180mV (Typ) Quiescent supply current — 50μA (x2) Shutdown current — 100nA Output noise — 100μVRMS /V Over-temperature protection Short-circuit protection Under-voltage lockout Internal output discharge 100W MLPD-UT8, 1.6mm x 1.2mm x 0.6mm package
The device has separate input, output and enable pins for each LDO channel. Using the lowest possible input voltage for each output voltage reduces the power loss for each rail. This improves overall package thermal performance and efficiency compared to single input voltage devices.
Applications
Consumer electronics Wearable & Portable electronics Cell phones GPS devices Set top boxes/HDTVs Communication electronics Industrial electronics
The device has fast turn-on and turn-off voltage slew rate for fast system start up and reset response. Low quiescent current extends battery life. The SC563 family of devices provide protection circuitry such as short-circuit protection, under-voltage lockout, and thermal protection to prevent device failures. Stability is maintained by using 1µF capacitors on the output pins. The MLPD-UT8 1.6mmx1.2mm package and small ceramic bypass capacitors minimize the required PCB area.

SC563 Applications Information General Description The SC563 is a dual output linear regulator with low dropout voltage, low supply current, and low output noise. The device provides a simple, low cost solution with minimal PCB area. It has a miniature package size and needs four 1µF 0402 size external capacitors for its input and output. The dual LDOs are powered from separate input supply pins. Each LDO provides up to 300mA output current.

V out
140 -510 µs
Power On and Off Control and Turn-on Delay The SC563 device has separate enable pins (EN1 and EN2) that control the LDO outputs respectively. Pulling enable pin high will enable the device when the Vin is above the its UVLO level at about 2.4V. Pulling this pin low causes the device to shutdown where it typically draws 100nA from the input supply. When the enable pins are connected to the input voltage supply, the device turn-on and turn-off has two voltage thresholds to overcome. At the turn-on event, the enable pin voltage needs to be greater than the enable threshold and the Vin voltage needs to be higher than the UVLO. The higher of the two voltages, which is the UVLO, determines the turn on time. At turn-off, the first condition of either enable threshold low or the VIN UVLO will determine the turn-off event. After the enable goes high, the IC has a delay time before the output voltage ramps up. The delay is typically between 120µs to 510µs. The 510µs is related to the lower Vin condition. With 1uF output capacitor (capacitor part number: GRM155R61A105KE15) at no load conditions, the output voltage ramp time is typically at 15µs. The device has an internal discharge MOSFET to discharge the output voltage at disable, the typical discharge time is at 2ms. The enable and disable waveforms are illustrated in Figure

Figure 1 — Timing Diagram
The Output Noise LDO’s noise generally is characterized through noise spectral density (NSD) and total RMS value in the frequency band between 10Hz to 100KHz. The noise spectral density can be measured using a network analyzer with active probes. The RMS noise value is obtained from the noise spectral density curve by taking the square root of the area within the frequency range from 10Hz to 100kHz. The normalized output noise for SC563 is at a typical value of 100µVrms/V. The generalized output voltage noise can be approximated by: Vrms=Vout*100 µV.
Protection Features The SC563 provides protection features to ensure that no damage is incurred in the event of a fault condition. These functions include:
• • •
Under-Voltage Lockout Over-Temperature Protection Short-Circuit Protection with peak and foldback current limit
12
SC563
Under-Voltage Lockout The Under-Voltage Lockout (UVLO) circuit protects the device from operating in an unknown state if the input voltage supply is too low. When either VIN drops below the UVLO threshold, as defined in the Electrical Characteristics section, the corresponding LDO is disabled. The LDO is re-enabled when VIN is increased above the hysteresis level. When powering up with VIN below the UVLO threshold, the LDO remains disabled. Over-Temperature Protection Over-Temperature protection are separately available on both LDOs. An internal Over-Temperature (OT) protection circuit monitors the internal junction temperature. When the temperature exceeds the OT threshold as defined in the Electrical Characteristics section, the OT protection disables the corresponding LDO output. When the temperature drops below its hysteresis value, the LDO output will resume. Short-Circuit Protection Each output has short-circuit protection with peak current limit and fold back current limit. If the output current exceeds the peak current limit, the output voltage will drop and the output current will be limited to its fold back current limit value. See the waveforms in the typical operation section. If the short circuit is removed or the load current reduces to below the fold back current limit, the LDO output will rise back into regulation.
Component Selection
and stable temperature coefficients. Tantalum capacitors and Y5V capacitors are not recommended.
Thermal Considerations Although each of the two LDOs in the SC563 can provide 300mA of output current, the maximum power dissipation in the device is restricted by the miniature package size. The graphs in Figures 2 can be used as a guideline to determine whether the input voltage, output voltages, output currents, and ambient temperature of the system result in power dissipation within the operating limits are met or if further thermal relief is required. 2.5 TJ=150°C

Figure 2 — Maximum PD vs. TA
The following procedure can be followed to determine if the thermal design of the system is adequate. The junction temperature of the SC563 can be determined in known operating conditions using the following equation:
SC563 is designed for PCB savings with small area. The recommended input and output capacitor is 1μF with 0402 package with part number GRM155R61A105KE15.
TJ = TA +(PD x θJA)
Although there is no maximum value of output capacitor specified, very large values may increase the rise time of the output voltages without affecting stability. It is recommended that the value of output capacitance be restricted to a maximum of 10μF. Ceramic capacitors of type X5R or X7R should be used because of their low ESR

SC563 Applications Information (continued) Example A SC563LH is used to provide outputs of 3.3V, 150mA from LDO1 and 1.8V, 250mA from LDO2. The input voltage is 4.2V for LDO1 and 2.5V for LDO2, and the ambient temperature of the system is 60°C. PD= 0.15X(4.2 – 3.3) + 0.25X(2.5 – 1.8)
Layout Considerations The diagram in Figure 3 below illustrates proper layout of a circuit. The layout considerations are listed below:
• •
= 0.31W and TJ = 60 + (0.31 x 90) = 87.9°C This calculation shows the junction temperature is 87.9°C and it is below the maximum junction temperature of 125°C for this power dissipation. This example also demonstrates that with separate input voltages for LDO1 and LDO2, the total power dissipation can be reduced with the lower LDO output voltage fed by a lower input voltage.
•
Attach the thermal pad of the device to a copper pad with vias connected to the GND plane. This enables better heat transfer from the device to the PCB. Place the input and output capacitors close to the device for optimal transient response and device behavior. Extra copper trace length between the device input and output to the capacitor soldering pad introduces parasitic inductance. Connect all ground connections of the input and output capacitor directly to the ground plane whenever possible to minimize ground potential differences on the PCB. Shown in the evaluation board layout below, the SC563 thermal pad, ground pins, and the input and output capacitors are all connected to the ground plane through vias .
