MCP1810 Ultra-Low Quiescent Current LDO Regulator Features Description Ultra-Low Quiescent Current: 20 nA (typical) The MCP1810 is a 150 mA (for V 3.5V), 100 mA (for R V 3.5V) low dropout (LDO) linear regulator that Ultra-Low Shutdown Supply Current: R provides high-current and low-output voltages, while 1nA(typical) maintaining an ultra-low 20 nA of quiescent current 150 mA Output Current Capability for V 3.5V R during device operation. In addition, the MCP1810 can 3.5V 100 mA Output Current Capability for V R be shut down for an even lower 1 nA (typical) supply Input Operating Voltage Range: 2.5V to 5.5V current draw. Standard Output Voltages (V ): 1.2V, 1.5V, 1.8V, R The MCP1810 comes in 11 standard fixed 2.0V, 2.2V, 2.5V, 2.8V, 3.0V, 3.3V, 3.5V, 4.2V output-voltage versions: 1.2V, 1.5V, 1.8V, 2.0V, 2.2V, Low Dropout Voltage: 380 mV maximum at 2.5V, 2.8V, 3.0V, 3.3V, 3.5V and 4.2V. 150 mA The 150 mA output current capability, combined with Stable with 1.0 F Ceramic Output Capacitor the low output-voltage capability, make the MCP1810 a Overcurrent Protection good choice for new ultra-long-life LDO applications Available in the following packages: that have high-current demands, but require ultra-low - 2 x 2 mm No Lead VDFN power consumption during sleep states. <4.0V) - 3 Lead SOT-23 (V The MCP1810 is stable with ceramic output capacitors R that inherently provide lower output noise and reduce - 5 Lead SOT-23 (V <4.0V) R the size and cost of the entire regulator solution. Only 1 F (2.2 F recommended) of output capacitance is Applications needed to stabilize the LDO. Energy Harvesting The MCP1810 ultra-low quiescent and shutdown Long-Life, Battery-Powered Applications current allows it to be paired with other ultra-low current Smart Cards draw devices, such as Microchips nanoWatt eXtreme Low Power (XLP) technology devices, for a complete Ultra-Low Consumption Green Products ultra-low-power solution.
