Note 1: See Figure 2-3 for correct capacity and ESR for stable operation.
2: CF is the filter capacitor for the external voltage supply.
3: This diode is only needed if CS/LWAKE is connected to a 12V supply.
4: Transient suppressor diode. Vclamp L = 43V.
5: These components are required for additional load dump protection above 43V.
6: Required if CPU does not have internal pull-up.
