UTC UT10XX
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.
