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 2.1V to 12.0V.
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.

Note:
²xx² stands for output voltages.
Both lead free and green compound devices are available. Note the symbol marks below:
²#² stands for lead free devices.
Blank and ²+² stands for green compound devices, which are Lead-free and Halogen-free.
For the TO92 package, the symbol mark will be at the end of the date code. Whereas for the SOT89 and
SOT23-5, the symbol mask will be located at the end of IC marking.
