General Description:
The MCP1702 is a family of CMOS low dropout (LDO),
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 voltage
range is specified up to 13.2V, making it ideal for lith-
ium-ion (one, two or three cells), 9V alkaline and other
three to six primary cell battery-powered applications.
The MCP1702 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 MCP1702 has a tight tolerance output voltage
regulation of ±0.5% (typ.) and very good line regulation
at ±0.2%/V. The LDO output is stable when using only
1 μF of output capacitance of either ceramic, tantalum
or
MCP1702 LDO also incorporates short circuit and
thermal shutdown protection to ensure maximum
reliability.
The MCP1702 device is offered in the 3-pin SOT-23A,
3-pin SOT-89, and 3-Pin TO-92 package options with a
temperature range of -40°C to +125°C.
