General Description

The HT73xx series is a set of three-terminal, low

power, high voltage regulators implemented in

CMOS technology. The series features extremely

low quiescent current which is typically 3.5μA .

They allow input voltages as high as 12V. The device

provides large current with a significantly small

dropout voltage.

The HT73xx consists of a high-precision voltage

reference, an error correction circuit, and a current

limited output driver. They are available with several

fixed output voltages ranging from 1.8V to 5.0V.

CMOS technology ensures low dropout voltage

and low current consumption. Although designed

primarily as fixed voltage regulators, these devices

can be used with external components to generate

variable voltages and currents.
