This circuit uses a step-up switch-mode regulator, which is usually used to produce a positive supply, to generate a regulated negative output voltage. The device used here is the MIC4680 from Micrel, ...

It couldn’t be simpler but you have to admit that a small adjustable portable power supply like this one will be really handy. The main part of the PSU is an LM317 linear voltage regulator which we’re ...

The 7805 voltage regulator is a great device if you want a simple way of bringing a voltage down to 5V. It’s a three-pin, one-component solution that puts out five volts and a lot of heat. Simple, not ...

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

The IXD1415 is a dual LDO regulator with on/off switch offering low power consumption voltage regulator. It has low ESR ceramic capacitor compatible and short circuit protection. The IXD1415 is a dual ...

Although microcontrollers generally run at low voltages, such as 3.3 V, they often need to control loads running at higher voltages like 12 V. If switching the low side isn’t an option, the ...

Switch-mode power supplies switch with a frequency that is either fixed, adjustable, or synchronised to an external clock. The value of the switching frequency determines the physical size and, ...
