The 5V 0.5A Power Supply Circuit Diagram is essentially a constant source modified by the feedback components R2 and R3 to give a constant voltage output. The output of the ZN424E need only be 2 volts above the negative rail, by placing the load in the collector of the output transistor Tr2. The current 5V 0.5A Power Supply Circuit Diagram is achieved by Trl and R5. This simple circuit has the following performance characteristics: Output noise and ripple (full load) = 1 mV rms. Load regulation (0 to 0 A) = 0%. Temperature coefficient — ± 100 ppm/°C. Current limit = 05 A.
