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 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 (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.
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.
