MC33375: Linear Voltage Regulator, LDO, 300 mA, with On / Off Control
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.
Features- Low Quiescent Current (0.3 mA in OFF mode; 125 mA in ON mode)
- Low Input-to-Output 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 Voltage
- Internal Current and Thermal Limiting
- Logic Level ON/OFF Control
