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.
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to
obtain variable voltages and currents.
71XXA-1 (for TO92)
71XX-1 (for SOT89)
1XX1 (for SOT23-5)
²XX² stands for output voltages.
For lead free devices, TO92 package will add a ²#² mark at the end of the date code, whereas SOT89 &
SOT23-5 packages will add a ²#² mark at the end of the marking.
