DESCRIPTION

DESCRIPTION

The US1010 is a low dropout three terminal adjustable

regulator with minimum of 1A output current capability.

This product is specifically designed to provide well regu-

lated supply for low voltage IC applications such as high

speed bus termination and low current 3.3V logic

supply. The US1010 is also well suited for other appli-

cations such as VGA and sound cards. The US 1010 is

guaranteed to have <1.3V drop out at full load cur-

rent making it ideal to provide well regulated outputs of

2.5V to 3.6V with 4.75V to 7V input supply.
