Output current is rated 10 mA, enough to bias the reference input of multiple ADCs or a small sensor bridge without an external buffer. ## Input range and supply current — fitting the rail budget Input voltage range is 5.2 V to 18 V, so it works from a 5.5 V regulated rail up to a 12 V or 15 V system bus. The 1.2 mA quiescent supply current is low enough that the reference does not dominate the power budget in a multi-rail design. The series topology means the output is always within the input minus dropout — no external resistor needed, unlike a shunt reference. ## Package and footprint — 8-SOIC layout notes The surface-mount package is compatible with reflow soldering and common pick-and-place equipment.","metaTitle":"REF5050AIDR 5V Series Voltage Reference, ±0.1%, 8ppm/°C","metaDescription":"Texas Instruments REF5050AIDR precision 5V series voltage reference. ±0.1% initial accuracy, 8ppm/°C drift, 3µVp-p noise.
