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.
