Description

The MCP1802 is a 300 mA, high PSRR, ceramic output capacitor stable Low Dropout (LDO) voltage regulator with shutdown. MCP1802 provides a low noise, highly stable output due to its excellent transient response while consuming only 25 µA of quiescent current. MCP1802's overcurrent limit with current foldback provides short-circuit protection.
