10.3.2 VCCOUT Pin

An internal LDO provides power for the integrated CAN transceiver and the VCCOUT output pin. The amount of current that can be delivered externally is dependent upon the CAN transceiver requirements during normal operation as well as the ambient operating temperature. When a CAN bus fault takes place that requires additional current from the LDO, the total available current to external load components may be degraded. During sleep mode the LDO is disabled and no current can be delivered. Once the device leaves sleep mode and enters other active modes the LDO is enabled for normal operation. This pin requires a 10 μF external capacitor as close to the pin as possible.
