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.
