Outline Note
Package marking on this page is for sourcing reference. Confirm body size, pitch, and land pattern from the manufacturer datasheet before layout.

Applications

LM339PT is used on board power rails, industrial 12 V/24 V supplies, and point-of-load converters. Confirm VIN/VOUT, current, and the TSSOP-14 thermal pad before layout. Nearby bucks/LDOs need compensation and footprint review.

Procurement notes

Confirm the full ordering code, package (TSSOP-14), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.

FAQ

Where to buy LM339PT?

You can request LM339PT 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 LM339PT available?

Listed inventory shows 71,984 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 LM339PT?

The sourcing listing shows package TSSOP-14. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.

What are alternatives to LM339PT?

Potential alternatives include LM339PTR, LM339PT-CUT TAPE, LM339P 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.
