Forgot to mention the volt gauge sits good

Source a good second hand one. Or fit a Jaycar adjustable 5v PSU.
Correct, volt gauge is not dependant on the voltage regulator.

ffs Hanra , don't start this yes/no thing , we got over that at express ?
The 4514 works , but it comes un-insulated which means a box is needed and extra wires and rooting around whereas the the simple 3 pin with a ground tab will bolt into place with a minimum of fuss onto the die cast body of whatever it was bolted to as per fact. , from a vague memory lapse even the "pinger" type had it's body bolted to some sort of sink , who knows what the 4514 has "built in" in terms of thermal over load and correction ?

The 4514 works because it has a digital switching circuit which produces little or no heat and has inbuilt overload protection, very safe. Sure there's 3 wires to connect, but that's going to be the same with any external reg. The little 3 pin regs generate a lot of heat, require a decent (larger) heat sink, are unstable in terms of voltage output and are a fire risk imo. My recommendation is don't use them. The original "pinger" regs generate only a small amount of heat, no sink, as the heat is what makes them operate.

agree , the 3 pins do get warm when pulling around 875ma , without knowing what load they are under in heavy load conditions sort of makes it hard to work out how much they draw in heavy load conditions ? , either way , one or the other , personal choice , the "pinger' was a "digital " device
some clever engineering went into making those things , both back then and now .
