LDO regulator from Holtek for battery powered system

The HT71AXXXX devices are CMOS technology based TinyPower low dropout voltage regulators from Holtek with integrated voltage detector. The new HT71AXXXX devices are suitable for battery powered system, communication equipment, audio/video equipment, and home applications.

The key features of the HT71AXXXX devices are,

6uA typ of low supply current
Operating input voltage ranges from 12V max
Low temperature coefficient
30mA of voltage regulator output current
Voltage detector includes hysteresis
High output voltage accuracy of ±3%

Holtek says that with the inclusion of a voltage detector function in the same device reduces a two chip solution to a single chip solution resulting in reduced product costs. The voltage detector output is an N-channel open drain.

Package: 5-pin SOP89, 3-pin SOT89 package
