DESCRIPTION

The US1010-25 is a low dropout three terminal fixed out-

put regulator with minimum of 1A output current capabil-

ity. This product is specifically designed to provide well

regulated supply for low voltage IC applications as well

as generating clock supply for the PC applications. The

US 1010 is guaranteed to have <1.3V drop out at

full load current making it ideal to provide well regu-

lated with 3.8V input supply. The US1010 is specifically

designed to be stable with low cost Aluminimum ca-

pacitors while still maintains stability with low ESR tan-

talum caps as well.
