The input operating range is specified from 2.0V to 10.0V, making it an ideal choice for two to six primary cell battery-powered applications, 9V alkaline and one or two cell Li-Ion-powered applications. The MCP1801 is capable of delivering 100 m A with only 200 m V (typical) of input to output voltage differential (VOUT = 3.3V). The output voltage tolerance of the MCP1801 at +25°C is typically ±0.4% with a maximum of ±2%. Line regulation is ±0.01% typical at +25°C. The LDO output is stable with a minimum of 1 µF of output capacitance. Ceramic, tantalum or aluminum electrolytic capacitors can all be used for input and output. Overcurrent limit with current foldback provides short-circuit protection. A shutdown (SHDN) function allows the output to be enabled or disabled. When disabled, the MCP1801 draws only 0.01 µA of current (typical). The MCP1801 is available in a SOT-23-5 package.
