Application with External NPN Transistor for Increased VCC Current Demand
Application Circuit for Increased 5V Load Demands
100n
The VCC pin drives the base of an external NPN transistor. The voltage regulation is done via
the control loop over the sense input PVCC. Note that no current limitation is available in the
configuration shown above.

All open pins are MCM-IOs that can be used for application-specific purposes. The shown
connections between the LIN-system-basis-chips and the MCM require the software in the MCM
being programmed correspondingly.
