Description

The MCP1710 is a 200 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 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.
