DESCRIPTION
PRELIMINARY DATASHEET
APPLICATIONS
VGA & Sound Card Applications
Low Voltage High Speed Termination Applications
Standard 3.3V Chip-Set and Logic Applications
The US1010 is a low dropout three terminal adjustable
regulator with minimum of 1A output current capability.
This product is specifically designed to provide well regu-
lated supply for low voltage IC applications such as
high
speed bus termination and low current 3.3V logic
supply.
The US1010 is also well suited for other appli-
cations such as VGA and sound cards. The US 1010 is
guaranteed to have <1.3V drop out at full load cur-
rent
making it ideal to provide well regulated outputs of
2.5V to 3.6V with 4.75V to 7V input supply.
