Applications
LM317MS-TR is used on board power rails, industrial 12 V/24 V supplies, and point-of-load converters. Confirm VIN/VOUT, current, and the SOT-223 thermal pad before layout. Nearby bucks/LDOs need compensation and footprint review.
Procurement notes
Confirm the full ordering code, package (SOT-223), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.

FAQ
Where to buy LM317MS-TR?
You can request LM317MS-TR from SJ Chip via the RFQ form on this page or the site-wide RFQ. We confirm manufacturer (STMicroelectronics), package, quantity, and lead time on the quotation.
Is LM317MS-TR available?
Listed inventory shows 26,560 pcs. Lot, date code, and shippable quantity are confirmed on RFQ — treat the listing as availability to quote, not a guaranteed cart ship.
What is the package of LM317MS-TR?
The sourcing listing shows package SOT-223. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.
What are alternatives to LM317MS-TR?
Potential alternatives include LM317MDT-TR, LM317M-TR-E, LM317MX and other same-series or same-package listings — all require datasheet and pinout checks. These are similar stock for evaluation, not automatic drop-in replacements.
