General Description
The HT71XX series is a set of three-terminal
low power high voltage regulators implemented
in CMOS technology. They allow input voltages
as high as 24V. They are available with several
fixed output voltages ranging from 3.0V to
5.0V. CMOS technology ensures low voltage
drop and low quiescent current.
Although designed primarily as fixed voltage
regulators, these devices can be used with ex-
ternal components to obtain variable voltages
and currents.
