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.
