Description
The MCP1802 is a family of CMOS low dropout (LDO)
voltage regulators that can deliver up to 300 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 alka-
line and one or two cell Li-Ion-powered applications.
The MCP1802 is capable of delivering 100 mA with
only 200 mV (typical) of input to output voltage differen-
tial (V
OUT
= 3.0V). The output voltage tolerance of the
MCP1802 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 out-
put capacitance. Ceramic, tantalum or aluminum elec-
trolytic capacitors can all be used for input and 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 MCP1802 draws only 0.01 μA of current (typical).
The MCP1802 is available in a SOT-23-5 package.
