Semtech SC338A

Ultra-Low Output Voltage Dual Linear FET Controller

Add to Watch List

The SC338A is an ultra low output voltage dual power supply controller designed to simplify power management for notebook PCs.


  • Reference voltage options
    • ± 2.5% over -40°C to +85°C (SC338)
    • ± 1.5% over 0°C to +85°C (SC338A)
  • Two independent and fully adjustable outputs
  • Wide supply voltage range permits operation from 5 V or 12 V rails
  • Very low quiescent current (500 µA typical with both outputs enabled and 5 V input)
  • Indivdual enable control for each output
  • Individual power-good monitoring and signalling for each output
  • Gate drives from input supply enable use of N-channel MOSFETs
  • User-selectable dropout voltage
  • Individual under-voltage protection for each output
  • MSOP-10 surface-mount package


  • Notebook PCs
  • Simple dual power supplies
