MC33275/D
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 A)
Low Input–to–Output Voltage Differential of 25 mV at I
O
= 10 mA,
and 260 mV at I
O
= 300 mA
Extremely Tight Line and Load Regulation
Stable with Output Capacitance of only 0.33 F for 2.5 V Output
