DESCRIPTION
PRELIMINARY DATASHEET
APPLICATIONS
VGA & Sound Card Applications
Standard 3.3V Chip-Set and Logic Applications
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.
