New LDO with only 20nA quiescent current

The MCP1810 is a 150 mA (for VR ≤ 3.5V), 100 mA (for VR > 3.5V) low dropout (LDO) linear regulator that provides high-current and low-output voltages, while maintaining an ultra-low 20 nA of quiescent current during device operation. In addition, the MCP1810 can be shut down for an even lower 1 nA (typical) supply current draw.


  • Ultra-Low Quiescent Current: 20 nA (typical)
  • Ultra-Low Shutdown Supply Current:1 nA (typical)
  • 150 mA Output Current Capability for VR ≤ 3.5V
  • 100 mA Output Current Capability for VR  3.5V
  • Input Operating Voltage Range: 2.5V to 5.5V
  • Standard Output Voltages (VR): 1.2V, 1.8V, 2.5V,3.0V, 3.3V, 4.2V
  • Low Dropout Voltage: 380 mV maximum at 150 mA
  • Stable with 1.0 μF Ceramic Output Capacitor
  • Overcurrent Protection
  • Space Saving, 8-Lead Very Thin Plastic Dual Flat, No Lead Package, 2 x 2 mm Body VDFN
