Applications
LD1117STR 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 LD1117STR?
You can request LD1117STR 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 LD1117STR available?
Listed inventory shows 4,777,090 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 LD1117STR?
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 LD1117STR?
Potential alternatives include LD1117STR-CUT TAPE, LD1117STR LPC2919FBD14, LD1117S30 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.
