DUAL 6A AND 1A LOW DROPOUT

POSITIVE ADJUSTABLE REGULATOR

DESCRIPTION

FEATURES

The US1260 product using a proprietary processcom-

bines a dual low drop out adjustable output regulators in

a single package with one output having a minimum of

6A and the other one having a 1A output current capabil-

ity. This product is specifically designed to provide well

regulated supplies for low voltage ICs such as 3.3V to

1.5V and 2.5V supplies for the GTL+ termination

and the new clock for Pentium II applications.Other

Guaranteed <1.3V Dropout at 6A (output #2)

Guaranteed <0.6V Dropout at 1A (output #1)

Fast Transient Response

1% Voltage Reference Initial Accuracy

Built in Thermal Shutdown

APPLICATIONS

Providing a single package solution for GTL+

and High Speed Bus Termination

applications include low cost dual supply for proces-

sors such as Intel P55Cä where 2.8V and 3.3 V are

needed for the Core and the I/O supplies from the

5V input.
