MCP1702 250 mA Low Quiescent Current LDO Regulator Features: Description: 2.0 A Quiescent Current (typical) The MCP1702 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 250 mA of Input Operating Voltage Range: 2.7V to 13.2V current while consuming only 2.0A of quiescent 250 mA Output Current for Output Voltages 2.5V current (typical). The input operating range is specified 200 mA Output Current for Output Voltages < 2.5V from 2.7V to 13.2V, making it an ideal choice for two to Low Dropout (LDO) Voltage six primary cell battery-powered applications, 9V - 625 mV typical 250 mA (V = 2.8V) alkaline and one or two cell Li-Ion-powered OUT 0.4% Typical Output Voltage Tolerance applications. Standard Output Voltage Options: The MCP1702 is capable of delivering 250 mA with only 625mV (typical) of input to output voltage - 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, = 2.8V). The output voltage tolerance differential (V 3.0V, 3.3V, 4.0V, 5.0V OUT of the MCP1702 is typically 0.4% at +25C and 3% Output Voltage Range 1.2V to 5.5V in 0.1V maximum over the operating junction temperature Increments (50 mV increments available upon range of -40C to +125C. Line regulation is 0.1% request) typical at +25C. Stable with 1.0 F to 22 F Output Capacitor Output voltages available for the MCP1702 range from Short-Circuit Protection 1.2V to 5.0V. The LDO output is stable when using only Overtemperature Protection 1F of output capacitance. Ceramic, tantalum or aluminum electrolytic capacitors can all be used for Applications: input and output. Overcurrent limit and overtemperature shutdown provide a robust solution Battery-powered Devices for any application. Battery-powered Alarm Circuits Package options include the SOT-23A, SOT-89-3, and Smoke Detectors TO-92. 2 CO Detectors Pagers and Cellular Phones Package Types Smart Battery Packs 3-Pin SOT-23A Low Quiescent Current Voltage Reference 3-Pin SOT-89 PDAs V V IN IN Digital Cameras 3 Microcontroller Power MCP1702 MCP1702 Solar-Powered Instruments Consumer Products 1 2 3 1 2 Battery Powered Data Loggers GND V V GND V IN OUT OUT Related Literature: 3-Pin TO-92 AN765, Using Microchips Micropower LDOs, 12 3 DS00765, Microchip Technology Inc., 2002 AN766, Pin-Compatible CMOS Upgrades to Bipolar LDOs, DS00766, Bottom Microchip Technology Inc., 2002 View AN792, A Method to Determine How Much Power a SOT-23 Can Dissipate in an Application, GND V V DS00792, Microchip Technology Inc., 2001 IN OUT 2010 Microchip Technology Inc.
