31 / 203 page ![]() DocID029274 Rev 3 31/203 L9678P, L9678P-S Start-up power control 202 4.3.4 VDD5 linear regulator The VDD5 linear regulator provides 5 V system voltage derived directly from battery line with an external power transistor to reduce integrated circuit power dissipation. This voltage rail is used in case a 5 V micro-controller is adopted. The stability of the regulation loop is guaranteed by use of a small external capacitor. Current limitation is provided by means of controlling output current on BVDD5 pin. The external pass transistor gives the flexibility to easily address different current loads in case of different micro-controllers. The VDD5 regulator is enabled in the ACTIVE mode and continues operation in the PASSIVE mode using power from energy reserve. VDD5 supply is monitored for system reset (see Power On Reset and Reset in Section 4.4); voltage monitoring is based on a second redundant bandgap voltage reference. Figure 14.
