                                                                                                  The MCP1804T-5002I/MB from Microchip is a 150mA, 28V LDO regulator with shutdown in 3 pin SOT-89 package. The MCP1804 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 150mA of current while consuming only 50μA of quiescent current. The input operating range is specified from 2V 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. Overcurrent limit with current foldback 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).
