AIC1741

LOW DROPOUT ADJUSTABLE REGULATOR

SPEC NO: DS-1741-00

ꢀ FEATURES

ꢀ DESCRIPTION

ꢀ 1% Accuracy 1.235V Voltage Reference.

The AIC1741 is a low power precision adjustable

regulator with 80mA output capability. The device

can be used as a secondary regular to provide

feedback in a switching power supply.

ꢀ Fast Transient Response.

ꢀ Low Ground Current at 55µA.

ꢀ Wide Output Current Range, 10µA~80mA.

ꢀ Output Programmable from 1.235V~11V.

ꢀ Low Temperature Coefficiency.

ꢀ Error Flag Warns of Output Dropout.

The AIC1741 circuitry includes an internal wide

band amplifier, a precision bandgap reference,

and a PMOS output transistor. The feedback

input can be connected to an external resistor

divider to program the sensed output voltage.

The VOUT pin provides loop frequency

compensation when used as a part of a larger

servo system.

ꢀ APPLICATIONS

ꢀ Voltage Regulator for Pentium^®CPUs.

ꢀ Wireless Communication System.

ꢀ 5V to 3.3V Regulator for VGA Cards.

ꢀ Battery Powered Systems.

Although the device works as a stand-alone

regulator, it can also drive an NPN power

transistor to construct a high current low dropout

regulator, with only very minor current loss to

ground.
