Voltage Regulator - Low Dropout, On/Off Control 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 www.onsemi.com packages, SOT223 and SOP 8. These devices feature a very low quiescent current and are capable of supplying output currents up to LOW DROPOUT 300 mA. Internal current and thermal limiting protection are provided by the presence of a short circuit at the output and an internal thermal MICROPOWER VOLTAGE shutdown circuit. REGULATOR The MC33375 has a control pin that allows a logic level signal to turnoff or turnon the regulator output. MARKING Due to the low inputtooutput voltage differential and bias current DIAGRAMS specifications, these devices are ideally suited for battery powered computer, consumer, and industrial equipment where an extension of useful battery life is desirable. 4 SOT223 AYM 375xx ST SUFFIX 1 Features: CASE 318E Low Quiescent Current (0.3 A in OFF mode 125 A in ON mode) 1 Low InputtoOutput Voltage Differential of 25 mV at I = 10 mA, O and 260 mV at I = 300 mA O 8 Extremely Tight Line and Load Regulation 375xx SOIC8 8 ALYW Stable with Output Capacitance of only 0.33 F for 2.5 V Output D SUFFIX 1 CASE 751 Voltage 1 Internal Current and Thermal Limiting Logic Level ON/OFF Control A = Assembly Location Y = Year NCV Prefix for Automotive and Other Applications Requiring M = Date Code Unique Site and Control Change Requirements AECQ100 L = Wafer Lot Qualified and PPAP Capable W = Work Week xx = Voltage Version These are PbFree Devices = PbFree Package (Note: Microdot may be in either location) V V in out ORDERING INFORMATION See detailed ordering and shipping information in the Thermal & package dimensions section on page 11 of this data sheet.
