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 SOP8. 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 MC33375 has a control pin that allows a logic level signal to
turnoff or turnon the regulator output.
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 Quiescent Current (0.3 mA in OFF mode; 125 mA in ON mode)
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
