Reference Voltage
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A stable and precise voltage used as a standard for comparison or calibration in electronic circuits. It forms the basis for voltage regulation, analog-to-digital conversion, and threshold detection in power supply designs.
Example in context
“The LDO uses a precision bandgap reference voltage of 1.25V to generate the accurate 3.3V output required by the sensor.”
“LDO, sensör tarafından gereken doğru 3.3V çıkışını üretmek için 1.25V hassas bant aralığı referans voltajı kullanır.”
Where engineers use it
Engineers use reference voltage in voltage regulators, ADCs, and comparators. In power supply design, the feedback loop compares the output voltage against this reference to maintain regulation. Temperature stability and accuracy are key specifications.
Synonyms: voltage reference, Vref, bandgap reference
Practice: can you use “Reference Voltage” at work?
A power supply's output voltage drifts with temperature. After analysis, the reference voltage's temperature coefficient is identified as the cause. Propose a solution to improve stability.
Show a model answer
“Adjust the feedback divider to set the output voltage relative to the reference voltage.”
