THREE-TERMINAL LOW
POWER VOLTAGE
REGULATORS
DESCRIPTION
The UTC
UT10XX
series is a set of three-Terminal low power
voltage regulators implemented in CMOS technology. They are
available with several fixed output voltages ranging from
1.5V~7.0V. The advantage of CMOS technology is low voltage
dropout and low quiescent current.
Although designed primarily as fixed voltage regulators, these
devices can be used with external components to obtain
variable voltages and currents.
CMOS IC
FEATURES
* Low power consumption
* Low voltage dropout
* Low temperature coefficient
* Wide operating voltage (12V Max.)
