SNLS696A April 2021 – May 2021 TSER953
The TSER953 features three internal regulators that must be bypassed to GND. The VDDD_CAP, VDDDRV_CAP, and VDDPLL_CAP are the pins that expose the outputs of the internal regulators for bypassing. TI recommends that each pin has a 10-µF, 0.1-µF, and a 0.01-µF capacitor to GND. The 0.01-µF caps must be placed as close as practical to the bypass pins.
