MC33275, NCV33275
Voltage Regulator - Low
Dropout
300 mA
The MC33275 series are micropower low dropout voltage
regulators available in a wide variety of output voltages as well as
packages, SOT223, SOP8, DPAK, and DFN 4x4 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.
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.
Features
Low InputtoOutput Voltage Differential of 25 mV at IO = 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
