PRELIMINARY DATASHEET

DESCRIPTION

The US1010-33 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 such as

VGA , sound & DVD cards. The US 1010 is guaran-

teed to have <1.3V drop out at full load current

making it ideal to provide well regulated with 4.75V to

7V input supply. The US1010 is specifically designed to

be stable with low cost Aluminimum capacitors while

still maintains stability with low ESR tantalum caps as

well.
