Description
The MCP1710 is a 200 mA for V
OUT
< 3.5V, 100 mA for
V
OUT
> 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 MCP1710 can
be shut down for an even lower 0.1 nA (typical) supply
current draw. The MCP1710 comes in five standard
fixed output voltage versions: 1.2V, 1.8V, 2.5V, 3.3V
and 4.2V. The 200 mA output current capability,
combined with the low output-voltage capability, make
the MCP1710 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 MCP1710 is stable using 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 MCP1710’s ultra-low quiescent and shutdown
current allows it to be paired with other ultra-low current
draw devices, such as Microchip’s nanoWatt XLP
technology devices, for a complete ultra-low power
solution.
