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 […]
Temperature Regulator Circuits using IC LM335
There are many cases where it is desirable to actively regulate the operating temperature of an electronic assembly. Sometimes, it is imperative to dissipate the heat generated by the components (this is the case for the majority of microprocessors in our modern PCs). On the contrary, it is necessary to artificially increase the operating temperature […]
