Re: Nextion with KA78T05
toggle quoted messageShow quoted text
When dropping down voltage I always use more than one regulator in series to split the dissipation.
E.g. 7809 or 7808 from the nominal 12V then to the 7805 and bolt them to the aluminium case or to a heat sink with thermal compound.
They are cheap enough not to bankrupt you.
Take care when buying from Ali etc
