Ok now we have this LM5164 chip, and we want to drop voltage from 100V down to let’s say 12V, right? But we also need 1A output so we need to design everything properly. Now this chip is cool because it has ultra-low quiescent current (IQ) so it does not waste much power when it […]

AMS1117 1A LDO Voltage Regulator IC – 3.3V, 1.8V, 2.5V, 5V Regulators
In this post I will be talking about one famous voltage regulator IC called AMS1117. It is a 1 Amp Low Dropout (LDO) Linear Voltage Regulator and we can get it in both fixed output types and also adjustable output version. It is super small, easy to use and available in SOT-223 package mostly, which […]
IC LM7912, -12V Negative Voltage Regulator Explained
In this post we are going to learn about one super old but gold IC called LM7912 or simply IC 7912. This one is not positive regulator like 7805 or 7812, but it is negative regulator which means it gives -12V output and not +12V. If you are making op-amp circuits or dual power supply […]
IC 7815: Full Specifications, Working, Circuit Diagram
In this post I am going to talk about this very common but very useful voltage regulator IC, that is called IC 7815. This chip is from the famous 78XX series of fixed voltage regulators. So the “15” in this number means this IC will always try to give +15V DC output, no matter what […]
Simple Online UPS Circuit
In this post I have explained about the making of a simple online uninterruptible power supply (UPS) which guarantees a seamless transfer of AC mains supply to inverter mains supply for the load, due to the absence of cumbersome transfer switches or relays. What is an Online UPS As the name suggests, an online UPS […]
Programmable 35238-MP Timer Module? How to Use it
So this 35238-MP Multi-Function Timer module is an digital adjustable programmable timer which we can use it for doing time-based automation things. Inside it, there is a microprocessor that watches time very closely and makes the relay turn ON or OFF after a set time. So this thing is good when we want to turn […]
