Ultra-Low Output Voltage Dual Linear FET Controller

The SC338 is an ultra low output voltage dual power supply controller designed to simplify power management for notebook PCs.

Features


  • 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

Applications


  • Notebook PCs
  • Simple dual power supplies
