DESCRIPTION

SOT-25
SOT-89
The UTC UT71XX 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.
