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 […]
IC LM358 Datasheet and Specifications
In this post you will find the complete datasheet, pinout specifications of the IC LM358. This datasheet is written in simple language so that even the new hobbyists are able to grasp the technical details of the IC quickly. The IC LM358B offers two high-voltage (36V) amplifiers in a single chip making them cost-effective for […]
LM12 IC Datasheet, Application Circuits
LM12 is a power operational amplifier integrated circuit (IC) developed by National Semiconductor (now owned by Texas Instruments). It is designed for use in high-power audio amplifiers, servo amplifiers, and other high-current applications. Here are the electrical specifications and technical datasheet of the LM12: Electrical Specifications: Technical Specifications: Overall, the LM12 is a high-performance power […]
INA219 Current Sensor Circuit Diagram and Datasheet
In this post we are going to understand this sensor called INA219, and this one is like a full smart sensor. It not only tells how much current is flowing but also tells voltage, and also calculates power, all in digital form. That means it talks with microcontroller through I2C lines. It is like an […]
IC IR2184, IR21844 Half-Bridge Driver Circuit Diagram, Datasheet, Working
In this article we are going to learn about one very useful IC called IR2184 or IR21844. This one is a smart half-bridge gate driver IC which we can use for driving both high-side and low-side MOSFETs or IGBTs, mainly when we are making full bridge inverters, or DC motor controllers, or even induction heater […]
