Semtech SC2738

Ultra Low Dropout Dual Linear FET Controller

Add to Watch List

The SC2738 is an ultra low output voltage dual power supply controller designed to simplify power management for desktop PCs and graphics cards.


  • ± 3.5% reference voltage
  • 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


  • Desktop PCs
  • Graphics cards
  • Simple dual power supplies
