Power Evaluation Board User Guide
EN5311 PowerSoC
The board has pre-tinned pads for up to 2 additional output capacitors with either
0805 or 1206 footprint.
Capacitance above the 10uF minimum can be added if the transient performance
is not sufficient using the 10uF. Altera recommends a low ESR MLCC type
capacitor be used.
NOTE: Capacitors must be X5R or X7R dielectric formulations.
