- Ultra-low Quiescent Current: 250 nA (typical)
- Ultra-low Shutdown Supply Current
- Small Package Size to Help Reduce Bill of Material (BOM) Cost
- Stable With Cost-effective Ceramic Capacitor that Provides Lower Output Noise
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 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.
