adjustable power supply

The project presented here is a wide input voltage range non-isolated DC-DC Converter, that provides a regulated, adjustable output voltage. The operating input supply is 55V DC and output regulated from 1.2V to 50V DC. The project built using LM2576HVT-ADJ IC. Screw terminals provided for easy...

Fully Adjustable Power Supply Based on a National Semiconductor application note, this circuit uses an LM317 3-terminal regulator (REG1), chosen because of its built-in over-current and over-temperature protection. Its output is boosted up to just over 5A by the MJ2955 transistor (Q1). The...

LM317 is perhaps the most popular linear regulator for low-power supply applications. The circuit which is presented here is a compact power supply unit based on this popular linear regulator. It is an adjustable power supply unit and it is able to supply up to 2A at 1.3 to 25V where the desired...

Adjustable Power Supply A general purpose dc power supply When testing electronic projects a good adjustable power supply is indispensable. The LM317 provides the basis for a quality regulated dc power supply. This kit combines an LM317 with a thumbwheel potentiometer to allow you to...
