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.

Features
  • 150 mA Maximum Output Current
  • High PSRR: 70 dB typical @ 10 kHz
  • Low Drop Out Voltage, 200 mV (Typical) @ 100 mA
  • 25 µA Typical Quiescent Currents
  • Wide Input Operating Voltage Range: 2.0V to 10.0V
  • Stable with Ceramic Output Capacitors
  • Current Limit Protection
  • Shutdown pin
