Description
The MCP1810 is a 150 mA (for V_R ≤ 3.5V), 100 mA (for
V_R  3.5V) low dropout (LDO) linear regulator that
provides high-current and low-output voltages, while
maintaining an ultra-low 20 nA of quiescent current
during device operation. In addition, the MCP1810 can
be shut down for an even lower 1 nA (typical) supply
current draw.
The MCP1810 comes in six standard fixed
output-voltage versions: 1.2V, 1.8V, 2.5V, 3.0V, 3.3V
and 4.2V.
The 150 mA output current capability, combined with
the low output-voltage capability, make the MCP1810 a
good choice for new ultra-long-life LDO applications
that have high-current demands, but require ultra-low
power consumption during sleep states.
The MCP1810 is stable with ceramic output capacitors
that inherently provide lower output noise and reduce
the size and cost of the entire regulator solution. Only
1 µF (2.2 µF recommended) of output capacitance is
needed to stabilize the LDO.
The MCP1810 ultra-low quiescent and shutdown
current allows it to be paired with other ultra-low current
draw devices, such as Microchip’s nanoWatt eXtreme
Low Power (XLP) technology devices, for a complete
ultra-low power solution.
