How does an lm317 work
WebFeb 26, 2024 · The adjustable digital display regulated power supply is shown in Figure 4. Since the voltage output range of LM317 is 1.25~37V, Iadj in the voltage calculation formula is very small (50μA) and can be ignored. The resistance of the potentiometer is 2.2kΩ to meet the adjustment range of output voltage 1.25~15V. Webedit- they design it this way because TL431's and resistors are available in much tighter tolerances, than LM317's. Check the LM317 datasheet for the guaranteed min and max values of its internal "1.25 volt" reference. Then multiply that variability by four to get the variability of a 5V regulated output. Ick.
