152 / 193 page  Electrical characteristics STM32L475xx 152/193 DocID027692 Rev 2 IDDA(VREF BUF) VREFBUF consumption from VDDA Iload = 0 µA - 16 25 µA Iload = 500 µA - 18 30 Iload = 4 mA - 35 50 1. Guaranteed by design, unless otherwise specified. 2. In degraded mode, the voltage reference buffer can not maintain accurately the output voltage which will follow (VDDA - drop voltage). 3. Guaranteed by test in production. 4. The capacitive load must include a 100 nF capacitor in order to cut-off the high frequency noise. 5. To correctly control the VREFBUF inrush current during start-up phase and scaling change, the VDDA voltage should be in the range [2.4 V to 3.6 V] and [2.8 V to 3.6 V] respectively for VRS = 0 and VRS = 1.
