Ch.3 is a linear regulator circuit that is configured identically with ch.2 except for a backup switching circuit.
Figure 6
6 shows internal block configuration of ch.3.
Output voltage is determined by the following equation.
Internal V
REF
is 1.0 V.
External capacitor of pin 12 is intended to control rush current on power supply.
