This sourcebook contains 50 practical electronic circuits for power supply applications. It contains circuits designed as voltage regulators, limiters, current sources, monitors, converters, inverters, and some auxiliary circuits commonly used in power supply devices. You can combine several circuits into one large module to create a powerful electronic device specially designed for your exclusive project. Most circuits are in the voltage regulator category while some are auxiliary that can enhance or protect the power supply circuits.
The transistors used in the circuits have more than one possible equivalents. The pindesignations are also shown in details. This feature can help avoid unnecessary delays. The pins shown are either in the bottom view or front view of the transistor unless otherwise noted. Large transistors which cannot or not planned to be installed directly on the PCB must be installed on a heatsink. A dashed circle around a transistor means that the transistor must be heatsinked.
