Description
:
The MCP1702 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 250 m A of current while consuming only 2.0 µA of quiescent current (typical). The input operating range is specified from 2.7V to 13.2V, 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.
The MCP1702 is capable of delivering 250 m A with only 625 m V (typical) of input to output voltage differential (VOUT = 2.8V). The output voltage tolerance of the MCP1702 is typically ±0.4% at +25°C and ±3% maximum over the operating junction temperature range of -40°C to +125°C. Line regulation is ±0.1% typical at +25°C.
