MuRata 5v Switching Regulator 5v for Spectrum 128k “Toast Rack”

Modern voltage regulator that can replace the original 7805 component in the Toastrack models.

This item is a lot more efficient than the original 7805 and will run a lot cooler. Therefore the large metal heatsink can be removed as it will not be required.

Only suitable for 128K Toastrack models. Can be used in rubber key 48K models if modified for horizontal mounting.

Description

MuRata 5v Switching Regulator 5v for Spectrum 128k “Toast Rack”

A replacement for the cheap inefficient 7805 used in the Spectrum 128k “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.
Can also be used in the standard Spectrum 48k, but as this version of the MuRata regulator is unmodified it cannot be used on Spectrum 48k Issue2 boards (in a rubber-key case) as the regulator must be horizontally mounted due to space constraints. (See HERE for a version modded for horizontal mounting)
