General Description
The HT75XX-2 series is a set of three-terminal low
power high voltage implemented in CMOS technology.
They can deliver 100mA output current and allow an in-
put voltage as high as 24V. They are available with sev-
eral 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.
