Description

General part information

MCP1801 Series

Please consider this device: MCP1754. View Side By Side Comparison

The MCP1801 is a 150 mA, high PSRR, ceramic output capacitor stable Low Dropout (LDO) voltage regulator with shutdown. MCP1801 provides a low noise, highly stable output due to its excellent transient response while consuming only 25 µA of quiescent current. MCP1801's overcurrent limit with current foldback provides excellent short-circuit protection.
