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
alkaline
applications.
The MCP1802 is capable of delivering 100 mA with
only 200 mV (typical) of input to output voltage
differential (V
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
output capacitance. Ceramic, tantalum or aluminum
electrolytic 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.
