General Description
The SR75XXSM series is a set of three-terminal low power high voltage regulators implemented in
CMOS technology. They allow input voltages as high as 37V. 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.
