Without that, the junction-to-board thermal resistance rises and the 125°C limit becomes harder to hold under continuous operation. Surface-mount only, supplied on tape and reel. The 6-WFDFN package variant is the same footprint as the WSON — confirm the exact supplier device package code 6-WSON (1.5x1.5) when ordering the land pattern. ## Cross-shop note vs TLV803 family The TLV803EA29VDBZR and TLV803ED29DBZR are the closest functional peers — both are active-low, open-drain supervisors with a single monitored rail. If your system needs a known delay before the reset de-asserts, the TLV803 variants guarantee that window; the TPS389018DSET is chosen when the timeout is handled elsewhere or when the 1.8V threshold is the hard requirement.","metaTitle":"TPS389018DSET — TI 1.8V Supervisor, Active Low, 6-WSON","metaDescription":"Texas Instruments TPS389018DSET Simple Reset/Power-On Reset IC, 1.8V threshold, -40°C to 125°C, open-drain output, 6-WSON.
