Application Scenarios & Design Considerations

ADJUSTABLE INVERTING NEGATIVE OUTPUT CURRENT MODE PWM REGULATORS

Alternative Part Number

  • LT1175CS8 --: Negative adjustable low-dropout regulator in SO-8 with comparable current rating and pinout, widely used as a direct substitute for the ST755.
  • MC33761 --: Negative voltage regulator offering similar adjustable output and current capability, suitable replacement when layout allows minor pin adjustments.
  • LM337L --: Classic adjustable negative linear regulator with well-known behavior; usable alternative if package and thermal constraints are acceptable.
