Fiches techniques

The LM317D2T-TR is an industry workhorse voltage regulator that provides an output voltage depending on a resistor divider network connected between the output and the adjust pin. The LM317’s wide output range of 1.2V to 37V and the high current output of up to 1.5A make the LM317D2T-TR highly appropriate for many power applications including power supplies. The 0.1% line and load regulation combined with the multiple inbuilt protection circuits make the LM317D2T-TR a reliable regulator and the wide temperature operating range of 0°C to 125°C allows the LM317D2T-TR to operate in multiple environment types.
