Output current is rated at 4 mA — enough to bias a handful of op-amp inputs or a single ADC reference input, but not intended to drive external loads like a heater or heavy buffer. ## SOT-23-5 footprint and active lifecycle Packaged in a 5-lead SOT-23 (SC-74A) with supplier device package SOT-23-5 — the same footprint used across many low-power references, so a PCB layout for this part often accepts pin-compatible alternatives from other vendors without a board spin. Note RoHS non-compliance: the part is not RoHS-compliant, which may restrict use in markets requiring RoHS exemption or lead-free assembly.","metaTitle":"MAX6129AEUK50-T Analog Devices Voltage Reference, 5V Fixed","metaDescription":"MAX6129AEUK50-T series voltage reference, fixed 5V output, ±0.4% accuracy, 40ppm/°C drift, 10.5µA supply current.
