NTE1942 Variable voltage and current, 5 pin TO220

NTE1942 Variable voltage and current, 5 pin TO220

NTE1942 Variable voltage and current, 5 pin TO220

(OP)
Hello - I'm trying to cross reference back an NTE1942 linear voltage regulator.   I called NTE and they can't uncross a device.  Does this device look familiar to anyone that might know the original device?  

I've looked at most every Semiconductor Manufacturers linear regulators product line and don't see a match.  I've gone through some older data books I have and it doesn't come up their either.  I'd really the application/design notes for this.  Any help - much appreciated. TIA

Is that surprising?  NTE specializes in older and obsolete devices.  If it's obsolete, then there's not much point in knowing what the original device was.

Thanks IRstuff.  I came across the NTE part with a home project in mind and liked the variable voltage/current in a quick and easy package.  I wanted to keep a low cost trickle charge, ~1.5A, 13.5V, on a lead acid battery from a somewhat distant 24VAC 1250mA outdoor low voltage transformer (CODE enforcement).

The NTE1942 part has two more pins to play with, for adjusting current I'm guessing, than a LM317 - basic 1.5A adjustable voltage linear regulator.  If I could figure out how to modify an existing 'smart' trickle charger to work on 24VAC with ~1.5A output then it'd be for the better.  

A question I pose to my self now ..... will a Schumacher Might Mite charger operate off 24VAC?  What's the front end power circuit look like on these chargers?
