General Description
technology ensures low voltage drop and low
power high voltage regulators implemented in
quiescent current. Although designed primarily as
CMOS technology. They allow input voltages as
fixed voltage regulators, these devices can be
high as 18V. They are available with several fixed
used with external components to obtain variable
output voltages ranging from 2.1V to 5.0V. CMOS
