Switch Mode 5v Regulator - Unmodded, vertical mount (replaces 7805)

MuRata Switch Mode 5v Regulator for Spectrum 128 "Toast Rack"

A replacement for the cheap inefficient 7805 used in the Spectrum 128 "Toastrack". This high-efficiency switch mode regulator wastes very little power as heat so no heatsink connection is required. It mounts directly onto the PCB where the 7805-connector wires are soldered.

  • High efficiency 5v 1.5A output
  • Short circuit protection
  • Over current shutdown
  • Over temperature shutdown
  • Unmodified for direct-PCB vertical mounting in Toastrack Spectrum (instructions included).
  • Can also be used in the standard Spectrum48, but as this version of the MuRata regulator is unmodified it cannot be used on Spectrum48 Issue2 boards (in a rubber-key case) as the regulator must be horizontally mounted due to space constraints. (See the Spectrum Mods section for a version modded for horizontal mounting.)
