Active production — no end-of-life notice on record
The MAX1793EUE25+: No last-time-buy or discontinuation notice has been issued. ROHS3 compliant — the part ships with full RoHS declaration, no exemption conflicts for EU or California markets.
1 A output with 0.45 V dropout — headroom check
Rated for 1 A continuous output with a maximum dropout voltage of 0.45 V at full load. The input rail must stay at least 0.45 V above the target output voltage across the full load and temperature range, or the regulator falls out of regulation. Output is positive and configurable: adjustable from 1.25 V up to 5 V, or fixed at 2.5 V via the factory-trimmed option — one BOM position covers both with the same pinout.
16-TSSOP exposed pad — thermal management
Housed in a 16-TSSOP (0.173", 4.40 mm width) with an exposed pad. Supplied in tube — the ordering code MAX1793EUE25+ is the tube variant. The tape-and-reel suffix differs; confirm the reel quantity before committing to a pick-and-place line.
Industrial temperature range and protection
Built-in protection: over-current, over-temperature, and short-circuit. The regulator survives a sustained output short without damage; thermal foldback reduces current until the die cools. Quiescent current is 200 µA — low enough for battery-backed always-on rails. The enable pin lets the system shut the regulator down when the load is idle.
