DESCRIPTION
DESCRIPTION
The US1260 product using a proprietary process com-
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
applications include low cost dual supply for proces-
sors such as Intel P55C
where 2.8V and 3.3 V are
needed for the Core and the I/O supplies from the
5V input.
DUAL 6A AND 1A LOW DROPOUT
POSITIVE ADJUSTABLE REGULATOR
Notes: P55C is trade mark of Intel Corp.
Typical application of US1260 in the Pentium
ΙΙ™ design with the 1.5V output providing for GTL+ termination
while 2.5V supplies the clock chip.
