1. Description
The MCP1810T-18I/J8A is a 150 mA (for VR≤3.5V), 100 mA (forVR>3.5V) low dropout (LDO) linear regulator thatprovides high-current and low-output voltages, whilemaintaining an ultra-low 20 nA of quiescent currentduring device operation. In addition, the MCP1810 canbe shut down for an even lower 1 nA (typical) supplycurrent draw. The MCP1810 comes in 11 standard fixedoutput-voltage versions: 1.2V, 1.5V, 1.8V, 2.0V, 2.2V,2.5V, 2.8V, 3.0V, 3.3V, 3.5V and 4.2V. The 150 mA output current capability, combined withthe low output-voltage capability, make the MCP1810 agood choice for new ultra-long-life LDO applicationsthat have high-current demands, but require ultra-lowpower consumption during sleep states.The MCP1810 is stable with ceramic output capacitorsthat inherently provide lower output noise and reducethe size and cost of the entire regulator solution. Only1 μF (2.2 μF recommended) of output capacitance isneeded to stabilize the LDO.The MCP1810 ultra-low quiescent and shutdowncurrent allows it to be paired with other ultra-low currentdraw devices, such as Microchip’s nanoWatt eXtremeLow Power (XLP) technology devices, for a completeultra-low-power solution.
