Temperature Regulator Circuits using IC LM335

Last Updated on January 3, 2024 by Swagatam Leave a Comment

temperature regulation using LM335 and Fan

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 […]
