                                                                                                  The MCP1703-5002E/DB is a CMOS low dropout Voltage Regulator that can deliver up to 250mA of current while consuming only 2μA of quiescent current (typical). The input operating range is specified from 2.7 to 16V, making it an ideal choice for two to six primary cell battery-powered applications, 9V alkaline and one or two cell Li-ion-powered applications. It is capable of delivering 250mA with only 625mV (typical) of input to output voltage differential (VOUT = 2.8V). The output voltage tolerance of the MCP1703 is typically ±0.4% at +25°C and ±3% maximum over the operating junction temperature range of -40 to 125°C. Line regulation is ±0.1% typical at +25°C. Output voltages for the MCP1703 range from 1.2 to 5.5V. The LDO output is stable when using only 1μF of output capacitance. Ceramic, tantalum or aluminium electrolytic capacitors can all be used for input and output.
