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

termination for Pentium Pro

cessor applications . The US1075 is also well suited for

other processors such as Cyrix

PC

<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.
