General Description

TheHT75xx-3seriesisasetofthree-terminal

lowpowerhighvoltageimplementedinCMOS

technology.Theycandeliver100mAoutputcurrent

andallowaninputvoltageashighas30V.Theyare

availablewithseveralfixedoutputvoltagesranging

from2.1Vto12.0V.CMOStechnologyensureslow

voltagedropandlowquiescentcurrent.

Althoughdesignedprimarilyasfixedvoltage

regulators,thesedevicescanbeusedwithexternal

componentstoobtainvariablevoltagesandcurrents.
