Adjustable power supply voltage regulator Ua723 integrated circuit based on the LM723 can be used in place between 0:50 volts 0.5 amps of current and voltage can be controlled over current and short circuit protection circuitry has long been ar umarımyap opportunity I can find. ‘ll Use the power transformer should be at least 5…

Interesting Power Supply Circuits Desings

| 2009/09/13

In 2007 I stumbled upon a very long time on a site I’ve found the power supply before you archive projects in time, but I want to share my archives for disorderly after a while 🙂 I just found files Circuits one most of us know by now that classical positive regulator IC on the…

TDA8138 Two Channel Multi Regulator Circuit 5V 12V

| 2009/02/15

TDA8138 Two Channel Regulator Circuit PCB printed circuit and schematic drawing of TDA8138 datasheet application prepared with eagle cad electronic drawing program. I used to wonder why they wouldn’t do this type of multi-output IC from time to time, but it wasn’t very popular or it didn’t come across to me.. TDA8138 features; Output current…

Voltage Current Regulated 2N3055 LM723 Power Supply

| 2009/01/18

Modification of the LM723 2N3055 stabilized power supply. I have always been concerned that the voltage drop is large when a load is applied and this is clearly visible even with a 30V voltmeter. (After adjusting the voltage with no load, 100 to 200mV drops when 3 to 4A load is applied) In particular, when…

High Voltage Laboratory Power Supply Circuit 50V to 450V 500mA

| 2008/10/27

High Voltage Laboratory Power Supply. The power supply we offer provides an adjustable voltage from 50 to 450 Volts at a current of 500 milliamps with 0.1% resolution. Residual ripple and noise value at 100Hz: <1 mV pp over the entire range. Internal resistance is < 0.5 Ω static and < 1 Ω dynamic from…

2.5v – 27.5v 2Amp Laboratory Power Supply Circuit

| 2008/10/23

The laboratory power supply circuit is similar to the classical transistor power supplies, the mosfet irfp150 is used as a power transistor, the author has placed the circuit in the pc power supply box, added a volt meter module, and a toroid transformer is used in the circuit, which can be used in normal sheet…
