Applications
Battery-powered equipment
Communication equipment
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.
Audio/Video equipment
General Description
The H75XX-H# series is a set of three-terminal
low power high voltage regulators implemented in
CMOS technology. They allow input voltages as
high as 40V. They are available with several fixed
output voltages ranging from 1.8V to 5.0V. CMOS
