How does a lm317 voltage regulator work
WebThese smaller pulse widths reduce (make less negative) the output voltage so that the output voltage is held constant. This increase causes pulse generator 142 to increase the pulse width of pulses amplified by pulse amplifier 125, which in turn causes the sense voltage on line 155 to become more negative as does the output voltage on line 134. This is how a LM317 regulator would look when connected to a circuit so that it supplies a constant DC voltage output. In this circuit, we add a … See more Now that you know the pins, how do we modify the voltage to that which we want output? We do this by changing the value of the resistor connected to the Adj pin of the voltage regulator. … See more The datasheet for a LM317 goes much more depth than this article, which was only created to serve as a beginner's guide to this voltage regulator.
