MCP1700T-2302ETT Microchip

MCP1700 Low Quiescent Current LDO Features General Description 1.6 A Typical Quiescent Current The MCP1700 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 250 mA of Input Operating Voltage Range: 2.3V to 6.0V current while consuming only 1.6A of quiescent Output Voltage Range: 1.2V to 5.0V current (typical). The input operating range is specified 250 mA Output Current for output voltages 2.5V from 2.3V to 6.0V, making it an ideal choice for two and 200 mA Output Current for output voltages < 2.5V three primary cell battery-powered applications, as well Low Dropout (LDO) voltage as single cell Li-Ion-powered applications. - 178 mV typical 250 mA for V = 2.8V OUT The MCP1700 is capable of delivering 250 mA with 0.4% Typical Output Voltage Tolerance only 178mV of input to output voltage differential (V =2.8V). The output voltage tolerance of the Standard Output Voltage Options: OUT MCP1700 is typically 0.4% at +25C and 3% - 1.2V, 1.8V, 2.5V, 3.0V, 3.3V, 5.0V maximum over the operating junction temperature Stable with 1.0 F Ceramic Output capacitor range of -40C to +125C. Short Circuit Protection Output voltages available for the MCP1700 range from Overtemperature Protection 1.2V to 5.0V. The LDO output is stable when using only 1F output capacitance. Ceramic, tantalum or Applications aluminum electrolytic capacitors can all be used for input and output. Overcurrent limit and overtemperature Battery-powered Devices shutdown provide a robust solution for any application. Battery-powered Alarm Circuits Package options include the SOT-23, SOT-89 and Smoke Detectors TO-92. 2 CO Detectors Pagers and Cellular Phones Package Types Smart Battery Packs 3-Pin SOT-23 3-Pin SOT-89 3-Pin TO-92 Low Quiescent Current Voltage Reference PDAs V V IN IN Digital Cameras MCP1700 3 Microcontroller Power 1 2 3 MCP1700 MCP1700 Related Literature 1 2 3 1 2 GND V V AN765, Using Microchips Micropower LDOs, GND V IN OUT OUT GND V V IN OUT DS00765, Microchip Technology Inc., 2002 AN766, Pin-Compatible CMOS Upgrades to BiPolar LDOs, DS00766, Microchip Technology Inc., 2002 AN792, A Method to Determine How Much Power a SOT23 Can Dissipate in an Application, DS00792, Microchip Technology Inc., 2001 2007 Microchip Technology Inc.
