General Description
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to
obtain variable voltages and currents.
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 2.1V to 5.0V. CMOS technology ensures
low voltage drop and low quiescent current.

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.
