Description
General part information
MCP1811 Series
The MCP1811/12 devices are 150 mA (MCP1811) and 300 mA (MCP1812) low dropout (LDO) linear regulators that provide high-current and low-output voltages while maintaining an ultra-low 250 nA of quiescent current during device operation. In addition, the MCP1811B/12B can be shut down for 5 nA (typical) supply current draw.
The MCP1811/12 family comes in nine standard fixed output-voltage versions: 1V, 1.2V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V, 3.3V, and 4.0V. The 150/300 mA output current capability, combined with the low output-voltage capability, make the MCP1811/12 device family a good choice for new ultra-long-life LDO applications that have high-current demands, but require ultra-low power consumption during sleep periods.
The MCP1811/12 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 for MCP1812) of output capacitance is needed to assure the stability of the system with a low noise output.
