Current Source / Regulator

Current Source/ Regulator

The Current Source/Regulator circuit powers the load through the regulator’s input rather than its output. Since the regulator’s output sees constant dummy load R1, it attempts to consume a constant amount of current, regardless of what the  voltage across the actual load really is. Therefore, the regulator’s input works as a constant current source for the actual load.

The current source circuit need power supply with any of the commonly available ± 15 or ± 12V . The voltage dropped over the regulator and dummy load lowered the total compliance voltage of the Current Source/ Regulator circuit. You set the load’s current with R1. The current equals 1.25 AAA x R.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
