Description

The MCP1702 is a CMOS low dropout positive voltage regulator with 250 mA maximum output. MCP1702 works with input voltage of up to 13.2V and in combination with its low current consumption of 2 A is an ideal solution for applications using multi-cell, 9V alkaline or one- or two cell lithium-ion batteries.

The MCP1702 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 250 mA of current while consuming only 2.0 A 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 mA with only 625 mV (typical) of input to output voltage differential (V_OUT = 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.

Output voltages available for the MCP1702 range from 1.2V to 5.0V. The LDO output is stable when using only 1 F of output capacitance. Ceramic, tantalum or aluminum electrolytic capacitors can all be used for input and output. Overcurrent limit and overtemperature shutdown provide a robust solution for any application.

Package options include the SOT-23A, SOT-89-3, and TO-92.
