1. A 10µF or higher ceramic capacitor must be connected between VDDIN and the closest GND pin of the device.
2. To ensure stability, an external 2.2µF output capacitor, CD
3. Defined as the current needed to charge external bypass/decoupling capacitor network.
4. At power-up VDDIO needs to reach 0.6V before VDDIN reaches 1.0V
5. VDDIO voltage needs to be equal or below to (VDDIN voltage +0.5V)
SAM4S
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 0.1 to 10 ohms.
Solid tantalum, and multilayer ceramic capacitors are all suitable as output capacitor.
A 100nF bypass capacitor between VDDOUT and the closest GND pin of the device helps decreasing output noise and
improves the load transient response.
