3 terminal regulator


Finding out some semiconductor shown in the photo, 0,5A 5V 3 terminal regulator in my junk box. I'm utilizing this regulator for the power supply on the Copen antenna booster, because it requires additional 5V supply to be activated as a booster.
The booster is set in VW 1302 Super Beetle for the recent FM and AM solid state radio in stead of original old style manually extended antenna and only AM push button preset National radio.
Another opinion actually occurs not to touch original condition on dash panel if the radio receiver is not so important and I do not have any inconvenience, because I'm watching one segment TV instead equipped in the Yupitel Radar Navigator.
Before that I should proceed to the replacement of regulator on the speedometer to control the fuel gauge accurately.
The original mechanical regulator equipped now control the fuel gauge stylus till a half position if the fuel tank was fulfilled.
The possibility that the signal sender unit may be wrong is not denied.
Careful checking must be necessary.
