LDO Regulator, 300 mA, High PSRR, with On/Off Control

Favorite

Overview

The MC33375 series are micropower low dropout (LDO) linear voltage regulators available in a wide variety of output voltages as well as packages, SOT-223,and SOP-8 surface mount packages. These devices feature a very low quiescent current and are capable of supplying output currents up to 300mA. Internal current and thermal limiting protection are provided by the presence of a short circuit at the output and an internal thermal shutdown circuit.

The MC33375 has a control pin that allows a logic level signal to turn-off or turn-on the regulator output.

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.
