The REF43 is a low-power precision reference providing a stable +2.5V output independent of variations in supply voltage, load conditions or ambient temperature. It is suitable as a reference level for 8-, 10- and 12-bit data acquisition systems, or wherever a stable, known voltage is required. Tight output tolerances and low thermal drift are assured by zener-zap trimming of both output voltage and its temperature coefficient. A unique curvature correction circuit reduces the thermal curvature which is characteristic of many previous bandgap references. * +2.5 Volt Output: ±0.05% Max * Low Temperature Coefficient: 10 ppm/°C Max * Excellent Regulation * Load Regulation: 20 ppm/mA Max * Line Regulation: 2 ppm/V Max https://elecena.pl/product/17760836/2-5v-low-power-precision-voltage-reference 2021-04-17 https://elecena.pl/product/17760836/2-5v-low-power-precision-voltage-reference 2025-01-17
