General Description
The HE75XXH series is a set of threeterminal 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 18V to 50V 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
