Product Overview
The Texas Instruments REF2030 is a dual-output voltage reference for Signal_Chain designs. It generates a 3.0 V reference output and a 1.5 V bias output, with the bias output specified as VREF / 2. Both VREF and VBIAS are specified for ±0.05% maximum accuracy at 25°C with VIN = 5 V and no load, and both outputs can sink and source ±20 mA.
Temperature behavior is defined by a ±13 ppm/°C typical and ±8 ppm/°C maximum output voltage temperature coefficient over -40°C to 125°C using the box method. VREF-to-VBIAS tracking is specified as ±1.5 ppm/°C typical and ±6 ppm/°C maximum from -40°C to 85°C, and ±2 ppm/°C typical and ±7 ppm/°C maximum from -40°C to 125°C.
The device is supplied in a SOT-23-5 DDC package with a 2.90 mm × 1.60 mm nominal body. Pins provide VBIAS, GND, EN, VIN, and VREF functions. The recommended input range is VREF + 0.02 V to 5.5 V at no load, with enable thresholds for shutdown and active operation.

Procurement Notes
When requesting a quote for REF2030, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
