DESCRIPTION
The US1050 product is a low dropout three terminal ad-
justable regulator with minimum of 5A output current
capability. This product is specifically designed to pro-
vide well regulated supply for low voltage IC applications
such as
Pentium
™
P54C
™
,P55C
™
as well as
GTL+
termination for Pentium Pro
™
and Klamath
™
pro-
cessor applications . The US1050 is also well suited for
other processors such as
Cyrix
™
,AMD and Power
PC
™
applications. The US 1050 is
guaranteed to have
<1.3V drop out at full load current
making it ideal to
provide well regulated outputs of 2.5V to 3.6V with 4.75V
to 7V input supply.
