General Description
The PJ71KXXSC series is a set of three-terminal
low power high voltage regulators implemented in
CMOS technology. They allow input voltages as high
as 24V. They are available with several fixed output
voltages ranging from 3.0V 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 external
components to obtain variable voltages and currents.
