DESCRIPTION
DESCRIPTION
The US1075 product is a low dropout three terminal ad-
justable regulator with minimum of 7.5A output current
capability. This product is specifically designed to pro-
vide well regulated supply for low voltage IC applications
such as Pentium
P54C,P55Cas well as GTL+
termination for Pentium Pro
and Klamathpro-
cessor applications . The US1075 is also well suited for
other processors such as Cyrix
,AMD and Power
PC
applications. The US 1075 is guaranteed to have
<1.2V drop out at full load current making it ideal to
provide well regulated outputs such as 3.3V with input
supply voltage as low as 4.5V minimum.
