products (Note 1)
Ordering Information
AP1186 is a 1.5A 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 a
switching regulator. One such application is the new graphic chip
sets that require anywhere from 2.4V to 2.7V supply.

Pin Descriptions
Name I/O
Description
Vsense
I
This pin is the positive side of the reference that allows remote load sensing to achieve excellent load
regulation. A minimum of 10uF capacitor must be connected from this pin to ground to insure stability.
Adj
(GND)
Vout
Vctrl
Vin
A resistor divider from this pin to the Vout pin and ground sets the output voltage.
(GND only for fixed mode)
O
The output of the regulator. A minimum of 100uF capacitor must be connected from this pin to ground
to insure stability.
This pin is the supply pin for the internal control circuit as well as the base drive for the pass transistor.
I This pin must always by higher than the Vout pin in order for the device to regulate. A minimum of
100uF capacitor must be connected from this pin to ground to insure stability.
The input of the regulator. Typically a large storage capacitor is connected from this pin to ground to
I insure that the input voltage does not sag below the minimum dropout voltage during the load
transient response. This pin must always be higher than Vout in order for the device to regulate.
