General Description

The HT75xx-7 is a low power high voltage series of regulators implemented in CMOS technology which has the advantages of low voltage drop and low quiescent current.

They allow input voltages as high as 30V and are available with several fixed output voltages ranging from 2.1V to 12.0V.

When the CE input is low, a fast discharge path pulls the output voltage low via an internal pull-down resistor.
