Description
The MCP1700 is a family of CMOS low dropout (LDO)
voltage regulators that can deliver up to 250 mA of
current while consuming only 1.6 A of quiescent
current (typical). The input operating range is specified
from 2.3V to 6.0V, making it an ideal choice for two and
three primary cell battery-powered applications, as well
as single cell Li-Ion-powered applications.
The MCP1700 is capable of delivering 250 mA with
only 178 mV of input to output voltage differential
(VOUT = 2.8V). The output voltage tolerance of the
MCP1700 is typically ±0.4% at +25°C and ±3%
maximum over the operating junction temperature
range of -40°C to +125°C.
Output voltages available for the MCP1700 range from
1.2V to 5.0V. The LDO output is stable when using only
1 F 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 SOT23, SOT89-3 and
TO92.
