AP1187

1A Ultra Low Dropout Positive Adjustable Regulator

Features

General Description

• Adjustable output voltage

• 0.6V Maximum Dropout voltage at 1.0A Load

current

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.

• Built-in Thermal Shutdown

• Output Current Limiting

• Fast transient response

• Good noise rejection

• Package: SOP-7L

Applications

• PC Motherboard

• LCD Monitor

• Graphic Card

• DVD-Video Player

• NIC/Switch

• Telecom Equipment

• ADSL Modem

• Printer and other Peripheral Equipment

Pin Assignments

Pin Descriptions

Name

Description

( Top View )

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 excellent load

regulation. A minimum of 10uF capacitor

must be connected from this pin to

ground to insure stability.
