The LR75XX- 1 series is a set of three-terminal high
current low voltage regulator implemented in CMOS
technology. They can deliver 100mA output current
and allow an input voltage 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.
