General Description

The APL5833 is a 3-pin low dropout linear regulator

with 2.0% accuracy of output voltage over line, load

and temperature variations. Dropout voltage at

300mA output current is less than 1.2V. Both output

current limiting and thermal shutdown are built in to

provide maximal protection to the APL5833 against

fault conditions. The over current and thermal shut-

down circuits become active when the current ex-

ceed 300mA, or the junction temperature reach

150°C. Normal operation is recovered when junction

temperature drops below 130°C.
