Advanced Power Electronics Corp. Technology Licensed from International Rectifier APU1050-33-HF-3 5A Low Dropout Fixed 3.3V Output Regulator Features Description Guaranteed < 1.3V dropout at full load current Fast transient response Voltage Reference Initial Accuracy of 1% Output Current Limiting Built-In Thermal Shutdown RoHS-compliant, halogen-free The APU1050-33-3 is a low dropout three-terminal 3.3V fixed output regulator with minimum output current capability of 5A . This product is specifically designed to provide well-regulated 3.3V supplies for low voltage IC applications. The APU1050-33-3 is guaranteed to have <1.3V dropout at full load current making it ideal to provide a well regulated output from inputs as low as 4.6V. Applications Standard 3.3V Chip Set and Logic Applications Ordering Information APU1050H-33-HF-3TR RoHS-compliant halogen-free TO-252 on tape and reel (3000 pcs/reel) APU1050S-33-HF-3TR RoHS-compliant halogen-free TO-263 on tape and reel (800 pcs/reel) APU1050P-33-HF-3TB RoHS-compliant halogen-free TO-220 in tubes Typical Application 5V C1 330uF VIN 3 OUT 2 APU1050-33V 3.3V / 5A C2 330uF Gnd 1 Figure 1 - Typical Application of APU1050-33-3 in a 3.3V regulator ©2010 Advanced Power Electronics Corp.
