Voltage Regulator - Low
Dropout, On/Off Control
300 mA
MC33375, NCV33375 Series
The MC33375 series are micropower low dropout voltage
regulators available in a wide variety of output voltages as well as

packages, SOT223 and SOP 8. These devices feature a very low
quiescent current and are capable of supplying output currents up to
LOW DROPOUT
300 mA. Internal current and thermal limiting protection are provided
by the presence of a short circuit at the output and an internal thermal MICROPOWER VOLTAGE
shutdown circuit.
REGULATOR
The MC33375 has a control pin that allows a logic level signal to
turnoff or turnon the regulator output.
MARKING
Due to the low inputtooutput 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. 4
