US1050

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 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.
