The 60 µA minimum cathode current keeps the device biased; below that, the output voltage drops out of regulation. Output current capability is 15 mA, which sets the ceiling for how much load current plus the bias current the shunt can sink while maintaining regulation. ## Noise floor and package fit The 0.1-10 Hz band is the flicker-noise region that matters for DC precision — a 16-bit ADC with a 3V reference sees roughly 0.5 LSB of noise from this source alone at the low end. The wideband noise figure helps estimate the total RMS noise in the signal chain when the reference is followed by an anti-aliasing filter. Housed in an SC-70-3 (SOT-323) package, the part occupies roughly 2.0 mm × 2.1 mm of board area. The three-pin footprint — cathode, anode, and no-connect — is standard for shunt references. The Tape & Reel packaging (7-inch reel, 3000 pieces) suits automated pick-and-place assembly.","metaTitle":"ADR5043BKSZ-REEL7 Shunt Voltage Reference, 3V ±0.1%, SC-70","metaDescription":"Analog Devices ADR5043BKSZ-REEL7 shunt voltage reference, 3V fixed output, ±0.1% tolerance, 75ppm/°C, SC-70-3.

The difference is the package: ADR5043BKSZ-REEL7 comes in SC-70-3, while ADR5043BRTZ-REEL7 is in SOT-23-3. The pinouts are different — SC-70 uses a different pin arrangement than SOT-23 — so a board designed for one package will not accept the other without a layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADR5043BKSZ-REEL7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADR5043BKSZ-REEL7 when reusing this data.
