Hello friends, I hope you all are doing great. Today, I am going to share the new Voltage Regulator Library for Proteus . Almost every circuit needs a steady supply voltage, and for decades the simplest way to get one has been a three-legged linear regulator : feed it 9 V or 12 V and it gives a clean 5 V or 3.3 V. The LM7805 and the LM317 are the two most famous, found on Arduino boards, in power supplies and in nearly every student's first project. They are easy to use, but they hide one trap that catches beginners again and again: the heat. Updates Voltage Regulator Library for Proteus Latest version: V1.0 (November 2026, this tutorial) Other component libraries: C945 Transistor · PC817 Optocoupler · Relay Module · Resistor · 5 mm LED · Designer Colour LED · Push Button · Active Buzzer · ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explore my knowledge about Introduction to LM317. It is basically a positive voltage regulator having three terminals. It can a supply a current more than 1.5A and voltage in a range of 1.25V to around 37V. You should also have a look at this LM 317 Calculator . For the adjustment of output voltage only two external resistors are required. It has improved standards of line regulation as well as load regulation. Full overload protection e.g. current limiting, area protection can be achieved using LM317. If its adjusting terminal is disconnected, even then all of the protection circuits will work properly. We can also use LM317 as precision current regulator by inserting a constant resistor between it ...
