The APL5885 is a 3-pin low dropout linear regulator with
2.0% accuracy of output voltage over line , load and temperature variations . Dropout voltage at 500mA output
current is less than 1.3V . Both output current limiting
and thermal shutdown are built in to provide maximal
protection to the APL5885 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 .
