General Description
The HT71XX-1 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 external components to
obtain variable voltages and currents.
