This uses a Zener diode and transistors. So easy to find parts and build easily it. Though very ancient, it still has many uses. Because it is classic and low noise circuit. So it can power to a general preamplifier or pre tone control using op-amp or transistor.
It is similar to the previous circuit.
These components are Unregulated supply section. Then, the current comes to a filtering regulator section. In positive regulator section up.
The Zener Diode keeps the voltage constant across the base of Q1. It is in a common collector.
So the voltage of the base equals the voltage of emitter VE. So, the output is fixed voltage about 15V. For negative regulator section is similar to positive different polarity only.
So they make V fixed voltage output. In this pin of the IC positive unregulated voltage is given in regulation. This pin is neutral for equally the input and output.
This difference between the input and output voltage is released as heat. The greater the difference between the input and output voltage, more the heat generated.
If the regulator does not have a heat sink to dissipate this heat, it can get destroyed and malfunction. So, we now have 2 options.
Either design your circuit so that the input voltage going into the regulator is limited to volts above the output regulated voltage or place an appropriate heatsink, that can efficiently dissipate heat. What to do with all the heat? A lot of energy is wasted in the form of heat.
If you are going to be using a heatsink, better calculate the heatsink size properly. On the other hand, energy actually being used is: 5 x 0. So twice the energy, that is actually utilized is wasted.
On the other hand, if 9V is given as input at the same amount of load: x 0. What we learn: Higher the input voltage, less efficient your will be. An estimated efficient input voltage would be at about 7.
