5A LOW DROPOUT POSITIVE
ADJUSTABLE REGULATOR
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 PentiumP54C,P55Cas well as GTL+
termination for Pentium Proand Klamathpro-
cessor applications . The US1050 is also well suited for
other processors such as Cyrix,AMD and Power
PCapplications. 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.
