The MCP1810T-35I/OT is a 150 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 MCP1810T-35I/OT can be shut down for an even lower 1 nA (typical) supply current draw. The MCP1810T-35I/OT 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 MCP1810T-35I/OT 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 MCP1810T-35I/OT 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 MCP1810T-35I/OT 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.
