A great top quality replacement for the 7805 5V 1A voltage regulator in ZX80, ZX81, ZX Spectrum 16K and 48K.
No heat, very power efficient.
As good as the Traco Power voltage regulators.
Pin compatible with the 7805.
Has a smaller footprint than the 7805, so fits at the location of the 7805 without any problem.
Offers the same power output as the standard 7805: 1A.
No heat, so no heatsink required.
Will increase the lifetime of your computer!
