It operates from a 2.55V to 5.5V input supply, drawing only 135µA quiescent current. The low noise floor — 33µVp-p from 0.1Hz to 10Hz and 48µVrms from 10Hz to 10kHz — makes it suitable for driving the reference input of a SAR ADC or a precision DAC without additional filtering. Housed in a SOT-23-3 package (also referenced as TO-236-3 or SC-59), the REF3125AIDBZT occupies minimal board area. Listed as Active by the manufacturer.","metaTitle":"REF3125AIDBZT Voltage Reference, 2.5V Fixed, ±0.2%, SOT-23-3","metaDescription":"Texas Instruments REF3125AIDBZT series voltage reference: 2.5V fixed output, ±0.2% tolerance, 20ppm/°C drift, -40°C to 125°C.
