Hi,
I was studying a voltage regulator circuit.
In that I found a small transformer of 3 terminals. So can anyone tell me about its use and function of terminals.

the terminals were connected to diode 1N4007, transistor,resistor in parallel with capacitor.
The circuit was also used to charge battery(1000mAh) and 1.1V.
The output voltage of circuit is 1.2V.
Thank You.

 

You don't really expect us to visualize a circuit from a verbal description do you? A schematic diagram is essential. A voltage regulator is a DC circuit and transformers don't work on DC. Now if any part of that transformer is connected to the mains it is inherently UNSAFE, because it provides no isolation.

 

sounds like a Time machine local oscillator, is there a yellow Flux capacitor as well...

Yellow was only used pre Y2K, now in accordance with MIL-D-41 they are blue.

Chetan22339, really it could have been any number of circuit designs using a center tapped transformer. Without seeing a drawing/schematic it is impossible to say.

The blue color comes from a change from unobtanium to Angelonium as the base material. This changed some of the performance characteristics, more than can be accommodated by a Detail. The correct spec is MIL-STD-41/B

Your probably talking about an auto transformer. 2 windings connected in series. 1 terminal is common to both windings.

sounds like an auto-transformer, they have a common terminal - they provide no isolation.

 

Maybe you have seen this

Could you show the schematic or whatever you looked at?
