MCP1810 20nA Ultra-Low Iq LDO – The MCP1810 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 MCP1810 can be shut down for an even lower 1 nA (typical) supply current draw. The 150 mA output current capability, combined with the low output-voltage capability, make the MCP1810 a good choice for new ultra-long-life LDO applications that have high-current demands, but require ultra-low power consumption during sleep states. Ceramic output capacitors 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. Need more infos? Ask your Semitron support and we will be pleased to help!
