The output voltage range of the LM317 is 1.25V-37V (the design output voltage range of this kit is 1.25V-12V), and the load current is up to 1.5A. Its use is very simple, only two external resistors are needed to set the output voltage. In addition, its linear regulation and load regulation are better than standard fixed voltage regulators. The LM317 has built-in protection circuits such as overload protection and safety zone protection.
To ensure the output performance of the regulator, R should be less than 240 ohms. The regulated voltage value can be adjusted by changing the RP resistance. D5, D6 are used to protect the LM317.
Output voltage calculation formula: Uo = (1 + RP / R) * 1.25
