DESCRIPTION

The US1261 product using a proprietary process com-

bines a dual low dropout regulators with fixed outputs of

1.5V and 2.5V in a single package with the 1.5V out-

put having a minimum of 6A and the 2.5V having a 1A

output current capability. This product is specifically de-

signed to provide well regulated supplies from 3.3V to

generate 1.5V for GTL+ termination resistor supply

and 2.5V clock supply for the new generation of

the Pentium II processor applications.
