MCP1804T-3302I/MB

The MCP1804 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 150 mA of current while consuming only 50 μA of quiescent current (typical, 1.8V ≤ VOUT ≤ 5.0V). The input operating range is specified from 2.0V to 28.0V. The MCP1804 is capable of delivering 100 mA with only 1300 mV (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 are stable with 0.1 μF of input and output capacitance. Ceramic, tantalum or aluminum electrolytic capacitors can all be used for input and output. Overcurrent limit with current foldback to 40 mA (typical) provides short circuit protection. A shutdown (SHDN) function allows the output to be enabled or disabled. When disabled, the MCP1804 draws only 0.01 μA of current (typical).
