General Description
AP1187 is a 1A regulator with extremely low
dropout voltage. This product is specifically
designed to provide well regulated supply for
applications requiring 2.8V or lower voltages from
3.3V ATX power supplies where high efficiency of a
switcher can be achieved without the cost and
complexity associated with switching regulator. One
such application is the new graphic chip sets that
require anywhere from 2.4V to 2.7V supply.

Pin Descriptions
Name
Description
ADJ
A resistor divider from this pin to the V
OUT
pin and ground sets the output voltage.
This pin is the positive side of the
reference that allows remote load
sensing
to
achieve
regulation. A minimum of 10uF capacitor
must be connected from this pin to
ground to insure stability.
The input of the regulator.
This pin is the supply pin for the internal
control circuit as well as the base drive
for the pass transistor.
Not used.
