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.
