Application Scenarios & Design Considerations

WITH ON-CHIP VOLTAGE REGULATOR

Alternative Part Number

  • MT9172 --: Microchip acquired Zarlink and offers functionally similar telecom interface devices; MT9172 is a well-known cross-reference for SP8792 applications.
  • HC55185 --: Renesas (formerly Intersil) provides telecom SLIC/interface ICs with comparable functionality and pinout options for SP8792 replacement.
  • LE88221 --: Microchip/Zarlink legacy telecom line interface device with similar feature set, suitable as a second-source alternative for SP8792 designs.
  • LM317 --: Widely available adjustable linear regulator that can serve as a functional substitute in many SP8792 applications, with broad second-source availability.
  • LT1086 --: Low-dropout adjustable regulator offering similar regulation performance and often used as a drop-in replacement in power supply designs.
  • MC33269 --: Adjustable low-dropout regulator with comparable current and voltage ratings, suitable as an alternative when the original part is unavailable.
