The MCP1804T-3302I/OT is a CMOS low dropout Voltage Regulator with shutdown can deliver up to 150mA of current while consuming only 50μA of quiescent current (typical, 1.8V = VOUT = 5V). The input operating range is specified from 2 to 28V. The MCP1804 is capable of delivering 100mA with only 1300mV (typical) of input to output voltage differential (VOUT = 3.3V). The output voltage tolerance of the MCP1804 at 25°C is a maximum of ±2%. Line regulation is ±0.15% typical at +25°C. The LDO input and output is stable with 0.1μF of input and output capacitance. Ceramic, tantalum or aluminium electrolytic capacitors can all be used for input and output. Over-current limit with current fold back to 40mA (typical) provides short-circuit protection. A shutdown (SHDN) function allows the output to be enabled or disabled. When disabled, the MCP1804 draws only 0.01μA of current (typical).
