Description
The MCP1710 is a 200 mA for VR 3.5V, 100 mA for
VR 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 eight standard,
fixed output voltage versions: 1.2V, 1.5V, 1.8V, 2V,
2.5V, 3V, 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 device’s ultra low quiescent and
shutdown current allows it to be paired with other ultra
low-current draw devices, such as Microchip’s XLP
technology devices, for a complete ultra low-power
solution.
