1. A 10 μF or higher ceramic capacitor must be connected between VDDIN and the closest GND pin of the device.
2. To ensure stability, an external 4.7μF output capacitor, CD
3. Defined as the current needed to charge external bypass/decoupling capacitor network.
SAM3U Series
This large decoupling capacitor is mandatory to reduce startup current, improving transient response and noise rejection.
GND pin of the device. The ESR (Equivalent Series Resistance) of the capacitor must be in the range 0.5 to 10 Ohms.
Solid tantalum, and multilayer ceramic capacitors are all suitable as output capacitor.
A 100 nF bypass capacitor between VDDOUT and the closest GND pin of the device decreases output noise and improves
the load transient response.
