MCP1701
4.0
The MCP1701 is a low quiescent current, precision,
fixed-output voltage LDO. Unlike bipolar regulators,
the MCP1701 supply current does not increase
proportionally with load current.
4.1
A minimum of 1 µF output capacitor is required. The
output capacitor should have an ESR greater than
0.1
above 1 MHz. Larger output capacitors can be used to
improve supply noise rejection and transient response.
Care should be taken when increasing C
that the input impedance is not high enough to cause
high input impedance oscillation.

4.2
A 1 µF input capacitor is recommended for most
applications when the input impedance is on the order
of 10 . Larger input capacitance may be required for
stability when operating from a battery input, or if there
is a large distance from the input source to the LDO.
When large values of output capacitance are used, the
input capacitance should be increased to prevent high
source impedance oscillations.
4.3
The MCP1701 internal circuitry monitors the amount of
current flowing through the P-channel pass transistor.
In the event of a short circuit or excessive output
current, the MCP1701 will act to limit the output current.
