Noise floor and power budget for sensitive analog chains
The REF3433MDBVTEP: The device draws 95 µA typical supply current and delivers up to 10 mA output current, so it can bias multiple ADC reference inputs or a low-power sensor bridge without exceeding the thermal budget of the SOT-23-6 package. Input voltage range is 3.35 V to 13 V, giving headroom for a regulated 5 V or 12 V rail to feed the reference while maintaining dropout margin.
It is ROHS3 compliant, meeting the latest EU restriction on hazardous substances for new designs shipping into regulated markets.
