MCP1700
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 碌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
(V
OUT
= 2.8V). The output voltage tolerance of the
MCP1700 is typically 卤0.4% at +25掳C and 卤3%
maximum over the operating junction temperature
range of -40掳C to +125掳C.
Output voltages available for the MCP1700 range from
1.2V to 5.0V. The LDO output is stable when using only
1 碌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.
