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.

Note 1 : Low duty cycle pulse testing with Kelvin connections are required in order to maintain accurate data.
Note 2 : Drop-out voltage is defined as the minimum differential voltage between Vin and Vout required to maintain
regulation at Vout. It is measured when the output voltage drops 1% below its nominal value.
