I preferred EasyPCB, I wonder if this is still going, but I was not the decision maker. Fortunately the owners of Proteus used to give us about 100 free student licences every year, probably as we spent a fortune on renewing the licence every year, but these only lasted a year. I was always telling my students not to use these as it was basically illegal and also against University policy (to use any unlicensed software). There are many cracked or unlicensed copies of Proteus about. Here are the links to our New Proteus Libraries: Step 1: Links to Download New Proteus Libraries So, let's get started with these New Proteus Libraries for Engineering Students: So, you can join our You Tube Channel to have a look at these Proteus Libraries. I have also designed their videos in which I have explained in detail How to use these Proteus Libraries. I am gonna share all those Proteus Libraries in this instructable so that Engineering Students can download them and use them in their Projects.

If you are looking for a linear buck voltage regulator that can drive 3A loads and provide an output in the range of 1.23V to 37V with an efficiency of 88% then you can use this IC.Hello friends, we have designed many Proteus Libraries on our blog The Engineering Projects which are not yet developed and we are really very proud that we are the first designers for these Proteus Libraries. This feature makes it ideal for designing switch-mode power supplies as it greatly simplifies their design. Due to its convenient use, it is also used as a step-down switching regulator. LM2576 is a 3A voltage regulator which provides an excellent line and load regulation. LM1117, CS51411, LM723, LM7912 Where to use 3A Step-Down Voltage Regulator? LM2576 Equivalent and Alternative Options It has an Undervoltage lockout circuit which keeps the input voltage in a range and keeps the regulator off until it comes to a certain threshold level.Protection circuitry includes thermal shutdown and current limit protection.Its output current is specified up to 3A.It can withstand a tolerance of ±4% on output voltage when the input voltage is in the range specified and output load conditions are satisfied, and tolerance of ☑0% on the oscillator frequency.The output voltage can be varied from 1.23V to 37V by connecting external components.This regulator can provide fixed output voltages of 3.3, 5, 12 and 15 volts.Input voltage can be applied up to 40V and up to 60V for HV versions.It is a fixed frequency voltage regulator having an internal oscillator of frequency 52kHz.To disable the regulator, connect this pin to HIGH logic. Connect it to the ground to enable the voltage regulator.
