The XL317 is an adjustable positive linear voltage regulator from Xinluda. It provides a programmable output from 1.25 V to 32 V at up to 100 mA in a SOP-8 package, using only two external resistors to set the output voltage.

What is the output current rating of the XL317?

The XL317 supplies up to 100 mA of output current, making it suited to lower-current adjustable rails and post-regulation rather than high-current loads.

What package does the XL317 come in?

The XL317 is supplied in a SOP-8 surface-mount package.

Is the XL317 the same as an LM317?

The XL317 uses the classic adjustable three-terminal positive-regulator concept (output set by two resistors with a 1.25 V reference), but it is a Xinluda part in a SOP-8 package rated at 100 mA - closer to the TL317 family than the 1.5 A TO-220 LM317. Always confirm pinout, current rating, and package against the Xinluda datasheet before substituting.

What protection features does the XL317 include?

The XL317 integrates current limiting, thermal overload protection, and safe-operating-area protection to guard against fault conditions.

How can I buy the XL317 if it is hard to find?

The XL317 has limited authorized-distributor availability. Pacific Component Xchange specializes in sourcing hard-to-find power-management ICs. Submit an RFQ and our team will provide current availability, lead time, and pricing.
