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 […]
Regulator
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 […]
USB 5V To 24V DC to DC Boost Power Regulator Module
This is a USB 5V to 24V Adjustable Boost Converter Module and it helps us step up a lower voltage into a higher voltage which we can adjust as needed. Now let us go through everything in detail step by step. Inputs – Where We Give Power Now we got three ways to power this […]
Step-Down Adjustable Voltage, Current Regulator Circuit using LM2673
The LM2673 series of regulators is a collection of monolithic integrated circuits that are designed to provide all the active functions needed for making a step-down, or buck converter, switching regulator circuit. This means that they are capable of driving loads of up to 3 amps while maintaining excellent line and load regulation characteristics. One […]
Adjustable Voltage Regulator Circuit using LM324 IC with Over Current Protection
In this post I have explained how a single LM324 IC can be used to create an adjustable voltage regulator circuit with overload and over current protections. Basic Working A basic IC LM324 quad operational amplifier regulates an unregulated 28-volt input source to approximately ±0.02%, resulting in a 1 amp 0 to -20 V supply. The […]
Simple Ceiling Fan Regulator Circuit
A simple electronic ceiling fan regulator circuit using a triac and a diac is a common type of circuit which is used to control the speed of a ceiling fan. This circuit basically works using phase control principle, in which the voltage supplied to the fan motor is varied by controlling the firing angle of […]
