Application Scenarios & Design Considerations

3-Terminal Adjustable Negative Regulator

Alternative Part Number

  • LT337MP --: Negative adjustable linear regulator in the same TO-3/TO-220 style package family with comparable current and voltage ratings; well-known drop-in style alternative for LM337 applications.
  • MC337T --: Negative adjustable voltage regulator rated for 1.5 A, functionally equivalent to the LM337 series and widely used as a second-source replacement.
  • KA337 --: Negative adjustable regulator with the same 1.5 A class rating and pin-compatible TO-220 package, commonly used as an LM337 substitute.
