General Description
The MCP1701A is a family of CMOS low-dropout,
positive voltage regulators that can deliver up to
250 mA of current while consuming only 2.0 µA of
quiescent current (typ.). The input operating range is
specified up to 10V, making it ideal for lithium-ion (one
or two cells), 9V alkaline and other two and three
primary cell battery-powered applications.
The MCP1701A is capable of delivering 250 mA with
an input-to-output voltage differential (dropout voltage)
of 650 mV. The low-dropout voltage extends the battery
operating lifetime. It also permits high currents in small
packages when operated with minimum V

differentials. The MCP1701A offers improved startup
and transient response.
The MCP1701A has a tight tolerance output voltage
regulation of ±0.5% (typ.) and very good line regulation
at ±0.2%. The LDO output is stable when using only
1 µF of output capacitance of either tantalum or
aluminum-electrolytic style capacitors. The MCP1701A
LDO also incorporates short circuit protection to ensure
maximum reliability.
Package options include the 3-pin SOT-23A, 3-pin
SOT-89 and 3-Pin TO-92.
