Fixed 2.5 V reference in a SOT-23-5 — what it delivers
The Analog Devices MAX6129BEUK25+T is a series voltage reference that holds its output at 2.5 V with ±1% initial tolerance. It draws only 5.75 µA supply current, making it a fit for battery-powered sensor nodes, portable instrumentation, and always-on ADC biasing where every microamp of quiescent draw matters. The 100 ppm/°C temperature coefficient keeps the output stable across the full -40°C to 85°C industrial range — enough headroom for outdoor telecom or factory-floor control without derating.
Input range and output drive
Input range spans 2.7 V to 12.6 V. The series topology delivers up to 4 mA output current.
Package and footprint
Supplied in a SOT-23-5 package, the part lands on a standard SOT-23-5 land pattern. Mounting is surface mount, and the part ships in Tape & Reel or Cut Tape options.
Lifecycle and sourcing
The MAX6129BEUK25+T carries an Active lifecycle status from Analog Devices, so there is no near-term EOL risk for new designs. The part is ROHS3 compliant. For BOM qualification, the ±1% tolerance, SOT-23-5 footprint, and 2.5 V output are the three specs that lock the fit — if those match the design, the rest of the ratings fall within typical margins.
