The REF5030AIDR is a Texas Instruments precision series voltage reference that delivers a fixed 3 V output with an initial tolerance of ±0.1% and a temperature coefficient of 8 ppm/°C.
Noise floor and drift — the specs that matter for precision chains
Input voltage spans 3.2 V to 18 V. Output current is rated at 10 mA. The 1.2 mA quiescent supply current keeps the power budget lean in battery-backed or always-on sections.
