We often use linear regulators in our designs. They are cheap and simple – you put the regulator chip itself on the board, add two capacitors, and get a voltage. Linear regulators are imperfect, of ...

Last time, we went over switching regulator basics – why they’re wonderful, how do you find a switching regulator chip for your purpose, and how to easily pick an inductor for one. Your datasheet ...

After clocks and resets, we like to focus on voltage regulator circuits when doing an EMC board review. Voltage regulators can cause both radiated emissions and susceptibility problems. Emissions are ...
