General Description

The APL5158 is a precise CMOS LDO with power ok

function. The APL5158 offers 2% output accuracy

over temp, and an ultra low ground current 60µA.

The power good function monitors the output voltage

and indicates when an error occurs in the system

(active low).In the event of an output fault such as

over current, thermal shutdown, the power ok output

is pulled low. The APL5158 also works with low-ESR

output capacitors, reducing the amount of board space

for power applications, critical in hand-held wireless

devices. Key features include current-limit, thermal

shutdown, fast transient response. A compact pack-

age SOT-23-5 is available for space saving purpose.
