MC33375, NCV33375 Series
300 mA, Low Dropout
Voltage Regulator with
On/Off Control
The MC33375 series are micropower low dropout voltage
regulators available in a wide variety of output voltages as well as
packages, SOT−223 and SOP−8. These devices feature a very low
quiescent current and are capable of supplying output currents up to
300 mA. Internal current and thermal limiting protection are provided
by the presence of a short circuit at the output and an internal thermal
shutdown circuit.

LOW DROPOUT
MICROPOWER VOLTAGE
REGULATOR
The MC33375 has a control pin that allows a logic level signal to
turn−off or turn−on the regulator output.
MARKING
DIAGRAMS
Due to the low input−to−output voltage differential and bias current
specifications, these devices are ideally suited for battery powered
computer, consumer, and industrial equipment where an extension of
useful battery life is desirable.
