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.
