THREE-TERMINAL LOW POWER
VOLTAGE REGULATORS

DESCRIPTION
The UTC UT10XX series is a set of threeTerminal 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.
SOT-89
Although designed primarily as fixed voltage
regulators, these devices can be used with external
components to obtain variable voltages and currents.
