General Description
The HT71AXXXX devices are CMOS technology volt-
age regulators which also include an internal voltage de-
tector. The functions of the voltage regulators include a
low dropout voltage, good output voltage accuracy as
well as the benefits of ultra-low supply current. The in-
clusion of a voltage detector function in the same device
reduce what would normally be a two chip solution to a
single chip solution resulting in reduced product costs.
For maximum application flexibility, the voltage detector
output is an N-channel open drain.
