It delivers up to 10 mA with a supply current of just 100 µA, making it suitable for precision analog circuits where both low power and a stable reference voltage are needed. Output tolerance is ±0.05%, and the temperature coefficient is 30 ppm/°C. Input voltage must stay between 5.05 V and 5.5 V. That 50 mV headroom above the 5 V output is the dropout floor — below it the reference falls out of regulation. ## Noise and precision for signal chains For a 5 V full-scale ADC, that 24 µVrms represents about 0.5 LSB of noise at 16 bits — the reference itself does not limit the converter's effective resolution. The series architecture means the REF4132B50DBVR does not require an external resistor to set the output current, unlike a shunt reference. The load current comes from the input rail, so the output stays at 5 V as long as the input stays above 5.05 V and the load stays below 10 mA. Housed in a 5-pin SOT-23 (SOT-753) package, the REF4132B50DBVR occupies about 3 mm² of board area. The SOT-23-5 footprint is standard — the same land pattern used for many op-amps and references in this package, so the layout is straightforward. The surface-mount package suits reflow soldering with standard profiles.","metaTitle":"Texas Instruments REF4132B50DBVR Series Voltage Reference","metaDescription":"Texas Instruments REF4132B50DBVR series voltage reference, fixed 5V output, ±0.05% tolerance, 10 mA output, SOT-23-5.
