Description:
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 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
applications.
The MCP1702 is capable of delivering 250 mA with
only 625 mV (typical) of input to output voltage
differential (V
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 µF of output capacitance. Ceramic, tantalum or
aluminum electrolytic capacitors can all be used for
input
overtemperature shutdown provide a robust solution
for any application.
Package options include the SOT-23A, SOT-89-3, and
TO-92.
