Introduction

AI Translation

The MCP1801 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 150 mA of current while consuming only 25 μA of quiescent current (typical). 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 mA with only 200 mV (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).
