The MCP1801 is a family of CMOS low dropout (LDO)
voltage regulators that can deliver up to 150 mA of
current while consuming only 25 μA of quiescent
current (typical). The input operating range is specified
from 2.0V to 10.0V, 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 MCP1801 is capable of delivering 100 mA with
only 200 mV (typical) of input to output voltage
differential (V OUT = 3.3V). The output voltage tolerance
of the MCP1801 at +25°C is typically ±0.4% with a
maximum of ±2%. Line regulation is ±0.01% typical at
+25°C.
The LDO output is stable with a minimum of 1 μF of

output. Overcurrent limit with current foldback provides
short-circuit protection. A shutdown (SHDN) function
allows the output to be enabled or disabled. When
disabled, the MCP1801 draws only 0.01 μA of current
(typical).
The MCP1801 is available in a SOT-23-5 package.
