ZSPM4141 Ultra Low Power Linear Regulator

The ZSPM4141 is an ultra low power linear regulator optimized for minimal quiescent current losses via advanced, proprietary technology. It can improve energy efficiency and reduce heat due to power dissipation because it draws low nA-level quiescent current for light loads, yet it can regulate current loads as high as 200 mA. The linear regulated output voltage is factory-configured to an option from 1.2V to 4.2V in 100mV steps. The ZSPM4141 also provides over-current protection.



  • Ultra low nA operating current with light loads
  • Best in class quiescent current of 20nA at ILOAD=0
  • Accurate output regulation


  • Low operating voltage: 2.5V to 5.5V
  • Power-down mode for 100 pA quiescent current
  • Over-current protection 250 mA
  • Output voltage options of 1.2V to 4.2V in 100 mV steps (programmed at manufacturing)
  • 8-pin DFN package (2mm x 2mm)
