General Description

The HT73XX series is a set of three-terminal, low power,

high voltage regulators implemented in CMOS technol-

ogy. The series features extremely low quiescent cur-

rent which is typically 3.5mA . 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 refer-

ence, an error correction circuit, and a current limited

output driver. They are available with several fixed out-

put voltages ranging from 1.8V to 5.0V. CMOS technol-

ogy ensures low dropout voltage and low current

consumption. Although designed primarily as fixed volt-

age regulators, these devices can be used with external

components to generate variable voltages and currents.
