• Wireless Communication Systems
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 shutdown circuits become active when the current exceed 300mA, or the junction temperature reach
150°C. Normal operation is recovered when junction
temperature drops below 130°C.
