APL1088 500mA Low Dropout Linear Regulator Features General Description • • • • • The APL1088 is a 3-pin low dropout linear regulator with 2.0% accuracy of output voltage over line , load and temperature variations. The output current capability of APL1088 is over 500mA. Dropout voltage at 500mA output current is less than 1.5V(max). Both output current limiting and thermal shutdown are built in to provide maximal protection to the APL1088 against fault conditions. The over current and thermal shutdown circuits become active when the current exceed 500mA , or the junction temperature reach 150°C. Normal operation is recovered when junction temperature drops below 130°C. Output Voltage Accuracy ± 2.0% Line Regulation - 1mV (typ.) Load Regulation - 6mV (typ.) Input Voltage Range up to 9V Internal Current Limiting and Thermal Shutdown Protections • SOT-89 and TO-92 Packages Available Applications • • • • • • • Voltage Regulator for CD-ROM Drivers 3 V IN 2 V out 1 ADJ APL1088 Voltage Regulator for LAN Cards Voltage Regulator for mother Boards 1 Wireless Communication Systems ADJ 2 VOUT 3 VIN Portable Instrument SOT-89 (Top View) Portable Consumer Equipment TO-92 (Top View) Low Voltage Systems Ordering Information APL1088 Package Code D : SOT-89 E : TO-92 Tem p.
