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 4mA. 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.
