Ch.5 is a linear regulator circuit that is configured identically with ch.2 except for a backup switching circuit.
Figure 6
9 shows an internal block configuration of ch.5.
Output voltage is determined by the following equation.
Internal V
REF
is 1.0 V.
External capacitor C53 of pin 39 is intended to control rush current on power supply.
1) On/off control
This regulator is capable of on/off control only with serial data.
Initial setting turns off at IC startup.
2) Supply voltage and GND
Power supply of this regulator is pin 46 (VB1) and GND is pin 6 (SGND).
