The MCP1811/12 devices are 150 mA (MCP1811) and 300 mA (MCP1812) Low Dropout (LDO) linear regulators that provide high-current and low-output voltages while maintaining an ultra-low 250 nA of quiescent current during device operation.

In addition, the MCP1811B/12B can be shut down for 5 nA (typical) supply current draw. The 150/300 mA output current capability, combined with the low output-voltage capability, make the MCP1811/12 device family a good choice for new ultra-long-life LDO applications that have high-current demands, but require ultra-low power consumption during sleep periods.

 

Key features

  • Ultra-low quiescent current: 250 nA (typical)
  • Ultra-low shutdown supply current
  • Small package size to help reduce bill of material cost
  • Stable with cost effective ceramic capacitor that provides lower output noise

 

Additional features

  • Extend battery life by consuming less current during standby or with light load
  • Output current capability: 150 mA for MCP1811A/B ; 300 mA for MCP1812A/B
  • Input voltage range: 1.8V to 5.5V
  • Standard output voltages (VR): 1.0V to 4.0V
  • Constant low dropout voltage: 550 mV
  • Stable with ceramic output capacitor: 1.0 μF (MCP1811) and 2.2 μF (MCP1812)
  • Overcurrent protection
  • Output discharge (shutdown mode, SHDN=GND)

 

Applications

  • Portable and IoT devices
  • Emergency kits
  • Home equipment
