AT32UC3A
6.2
Voltage Regulator
6.2.1
Single Power Supply
The AT32UC3A embeds a voltage regulator that converts from 3.3V to 1.8V. The regulator takes
its input voltage from VDDIN, and supplies the output voltage on VDDOUT. VDDOUT should be
externally connected to the 1.8V domains.
Adequate input supply decoupling is mandatory for VDDIN in order to improve startup stability
and reduce source voltage drop. Two input decoupling capacitors must be placed close to the
chip.
Adequate output supply decoupling is mandatory for VDDOUT to reduce ripple and avoid oscil-
lations. The best way to achieve this is to use two capacitors in parallel between VDDOUT and
GND as close to the chip as possible
Refer to Section 38.3 on page 765 for decoupling capacitors values and regulator characteristics
6.2.2
Dual Power Supply
In case of dual power supply, VDDIN and VDDOUT should be connected to ground to prevent
from leakage current.
