The LM317 is a popular adjustable voltage regulator integrated circuit (IC) that is widely used in electronic circuits. FAQs: What are the recommended capacitors to use with the LM317? Ans: The LM317 requires an input and an output capacitor for stability. A 0.1?F ceramic capacitor should be used at the input, and a 1?F tantalum or electrolytic capacitor should be used at the output. Can the LM317 be used as a current regulator? Ans: Yes, the LM317 can be used as a current regulator by using a current-limiting resistor at the output. The output current is then given by Iout = 1.25V/Rlimit. What is the difference between LM317 and LM7805?Ans: The LM317 is an adjustable voltage regulator that can provide a wide range of output voltages, whereas the LM7805 is a fixed voltage regulator that provides a fixed 5V output voltage. Additionally, the LM317 can handle higher input voltages and has built-in short-circuit and thermal overload protection, which the LM7805 does not have. |

3-TERMINAL ADJUSTABLE REGULATORS LM317
DESCRIPTION
3-TERMINAL ADJUSTABLE REGULATORS
The LM317 are adjustable 3-terminal positive-voltage regulators capable of supplying 1.5A over a differential voltage range of 3V to 40V. They are exceptionally easy to use and require only two external resistors to set the output voltage. Both input and output regulation is better than standard fixed regulators. In addition to higher performance than fixed regulators, these regulators offer full overload protection available only in integrated circuits. Included on t |
