Features
General Description
The APL5835 is a 3-pin low dropout linear regulator with
2.0% accuracy of output voltage over line , load and
temperature variations . Dropout voltage at 450mA out-
put current is less than 1.3V . Both output current limit-
ing and thermal shutdown are built in to provide maxi-
mal protection to the APL5835 against fault conditions .
The over current and thermal shutdown circuits become
active when the current exceed 450mA , or the junction
temperature reach 150
C . Normal operation is recov-
ered when junction temperature drops below 130
C .
Applications
