MCP1804 Low Dropout Voltage RegulatorThe Microchip MCP1804 is a Low Dropout (LDO) Voltage Regulator that operates from an input of 2.0 V to 28 V while delivering up to 150 mA of current. The device offers a low quiescent current of 50 μA and only 1 μF of output capacitance is sufficient to stabilise the output. The MCP1804 also has a Current Foldback feature to help protect the device.Features150 mA Output CurrentLow Dropout Voltage: 260 mV @ 20 mA, VR = 3.3 V (typical)50 μA Quiescent Current (typical)0.01 μA Shutdown Current (typical)Input Operating Voltage Range: 2.0 V to 28.0 VOutput Voltage Accuracy: ±2%Stable with Ceramic Output CapacitorsCurrent Limit Protection with Current FoldbackShutdown PinHigh PSRR: 50 dB Typical @ 1 kHzLDO (Low Dropout) Linear Voltage Regulators, Microchip
