6.5 Typical Powering Schematic

The SAM L10/L11 requires a single supply from 1.62V to 3.63V.

The following figures show the recommended power supply connections for two voltage regulators use cases:

LDO mode only
LDO/BUCK modes
Note: By default the LDO voltage regulator is enabled after any reset. Switching to BUCK mode is then required to benefit from its power efficiency.
