General Description
The APL5883 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 APL5883 against fault
conditions. The over current and thermal shutdown cir-
cuits become active when the current exceed 300mA,
or the junction temperature reach 150°C. Normal op-
eration is recovered when junction temperature drops
below 130°C.
