The 6.5 ppm/°C drift means the output shifts less than 3.25 mV over the entire -55°C to 125°C span. In an avionics data-acquisition chain, that keeps the gain error within the calibration budget without a lookup table. ## Supply headroom and load — sizing the rail Input voltage range is 5.2 V to 18 V, so the REF5050MDREP needs at least 200 mV of dropout above the 5 V output. On a 5 V rail that is already 5.0 V ±5 %, the minimum input is 4.75 V — which is below the 5.2 V floor, meaning a separate 5.2 V or higher supply is required. A 12 V or 15 V analog rail is the straightforward choice. Output is rated for 10 mA continuous. That covers the reference input of most SAR ADCs (typical draw 100 µA to 1 mA) plus any external buffer or divider. If the load exceeds 10 mA, a buffer amplifier is needed. ## Package and mounting — 8-SOIC footprint Housed in an 8-SOIC (0.154-inch width, 3.90 mm body) surface-mount package. The 1.27 mm pin pitch is layout-friendly on a 2-layer board. This part can be designed into new production without a near-term obsolescence contingency.","metaTitle":"REF5050MDREP Voltage Reference, 5V ±0.05%, 6.5 ppm/°C","metaDescription":"TI REF5050MDREP series voltage reference, fixed 5V output, ±0.05% tolerance, 6.5 ppm/°C drift, 15 µVp-p noise.
