APL1088

APL1088 500mA Low Dropout Linear Regulator Features • • • • • • 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 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.
