Supply current is 50 µA typical, making this reference suitable for battery-powered or always-on circuits where the reference must stay powered between conversions. ## Temperature drift and noise floor Low-frequency noise is 28 µVp-p (0.1 Hz to 10 Hz) and 80 µVrms (10 Hz to 10 kHz). These figures matter when the reference feeds a precision ADC — the noise integrates into the conversion result and the drift shifts the full-scale endpoint across temperature. ## Supply headroom and output drive Maximum output current is 25 mA, enough to bias a handful of ADC reference inputs or a small resistive divider network. ## Package and lifecycle Housed in a SOT-23-3 package (also known as TO-236-3, SC-59).","metaTitle":"REF3025AIDBZR Voltage Reference, 2.5V ±0.2%, SOT-23-3","metaDescription":"Texas Instruments REF3025AIDBZR series voltage reference, fixed 2.5V output, ±0.2% tolerance, 50µA supply current, -40°C to 125°C.
