Starting from a classical linear regulation, we will present the evolution towards a simple switching version. This will allow us to analyze the operation without going through the classical theoretical developments. In other words, a “practical” view of things. You can use the proposed design to significantly increase the backup time and efficiency of a […]

IC 7805, 7812, 7824 Pinout Connection Explained
In this post I have explained how to connect common 78XX voltage regulator ICs such as 7805, 7812, 7824 etc for getting fixed regulated output voltages at 5 V, 12 V, or 24 V outputs respectively. The input voltage must be at least 3 V higher than the desired output voltage. For example, if a […]
IC 7805 Variable Power Supply Circuit [5V to 15V]
Although, a 7805 IC is mostly used as a fixed 5 V voltage regulator, it is possible to configure a 7805 IC to produce a variable output from 5 V and higher, depending up the input DC supply. In this post I have explained a simple circuit network which can be used for getting an […]
