But when the adjust terminal and output terminal are tied together, the LM317 is converted to a two-terminal component which behaves equivalently to a 1.5V, high-current Zener diode. This concept can ...

We always enjoy [w2aew’s] videos, and his latest on zener diodes is no exception. In it, he asserts that all Zener diodes are not created equal. Why? You’ll have to watch the video belo… ...

Figure 3 Two LED drivers operating in series or parallel let you boost zener voltage or current. Figure 4 shows an assembled zener-diode-tester circuit. The zener diode under test is On Semiconductor ...
