General Description
The H73XX-A series is a set of three-terminal
low power high voltage regulators implemented in
CMOS technology. They allow input voltages as
high as 18V. The series features extremely low
quiescent current which is typically
2μA.
They are
available with several fixed output voltages
ranging from 2.5V to 5.0V. CMOS technology
ensures low voltage drop and low quiescent
current. Although designed primarily as fixed
voltage regulators, these devices can be used with
Note:”XX” stands for output voltages. Other
voltages can be
specially customized.
