Get many different voltages using the 7805 and Zener

 Get many different voltages using the 7805 and Zener

Protéus simulation of the +5V and -5V voltage regulators. Presentation of the 78xx and 79xx linear voltage regulator families. Presentation of the TSR 1-2450 regulator which replaces the 7805, same pinout, it supports 1A and has an efficiency of 96% (hardly heats up)

The 7805 is a voltage regulator that is intended to output 5V as long as it is powered by a higher voltage (at least 2V more). However, a zener diode can be used to add it's zener voltage to the output voltage (still needing a supply that is at least 2V higher than the new voltage).

Often our circuits are high voltage and if we have to install any low voltage device in the circuit so we can't have a separate supply for it or we have a high voltage power supply but we have to use a device and to test a project or there is a need to provide multiple voltages at one place, for example, 5V, 9V, 12V, etc. So for all these purposes, we can use only one three-point IC without any fuss. can obtain voltages of different quantities,

These ICs are common and very cheap and regulate the voltage by a fixed amount called fixed voltage regulator ICs.

Their numbers are L7805, L7809, and L7812.

And if you want to make a variable power supply of 1 to 37 volts DC, then you can use IC LM317 to convert any power supply to a variable power supply.

Watch the full video to know all these things in detail and how to use voltage regulators.
