1.25V fixed reference — 30 ppm/°C drift in a 1.5-mm QFN
The TS3312AQPR is a series voltage reference from STMicroelectronics, delivering a fixed 1.25 V output with ±0.15% initial accuracy and a 30 ppm/°C temperature coefficient. Maximum output current is 5 mA; the reference itself draws 10 µA quiescent. That low self-consumption keeps the thermal budget minimal in the 8-UFQFN (1.5×1.5 mm) package — no thermal pad required for normal operation.
Industrial temp range — footprint for dense analog front-ends
The 8-QFN (1.5×1.5 mm) supplier package places the die close to the load — useful when routing a clean 1.25 V reference to an ADC or DAC on a multi-layer board where trace length adds noise pickup. Surface-mount assembly with standard QFN reflow profile. The 1.5 mm body width fits under a 0.5 mm pitch QFN; the exposed pad on the underside (if present) should be connected to the ground plane for mechanical stability, though the low 10 µA supply current means the pad is not needed for heat sinking.
