6.3 On-Chip 1.8-V Voltage-Regulator Decoupling
The 1.8-V on-chip voltage regulator supplies the 1.8-V digital logic. This regulator requires decoupling
capacitors (C561, C321) and an external connection between them for stable operation.
6.4 Power-Supply Decoupling and Filtering
Optimum performance requires proper power-supply decoupling. The placement and size of the
decoupling capacitors and the power supply filtering are important to achieve the best performance in an
application. TI provides a recommended compact reference design for the user to follow.
