General Description
The AF75XXM series is a set of three-terminal low
power high voltage regulators implemented in
CMOS technology. They allow input voltages as
high as 15V. They are available with several fixed
output voltages ranging from 2.1V to 6.0V. 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.
