MC33275

Low Dropout 300 mA

Voltage Regulator

The MC33275 series are micropower low dropout voltage

regulators available in a wide variety of output voltages as well as

packages, DPAK, 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 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.

The MC33275 is available as a MC33375 which includes an On/Off

control.

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.

Features:

• Low Quiescent Current (125 mA)

• Low Input–to–Output Voltage Differential of 25 mV at I

O = 10 mA,

and 260 mV at IO = 300 mA

• Extremely Tight Line and Load Regulation

• Stable with Output Capacitance of only 0.33 mF for 2.5 V Output
