This VCOIN power supply is typically 3.0V and consumes approximately 8uA when VBAT is
disconnected.
4.4 Power Output
The SLM756P has multiple power outputs. For LCD, Camera, touch panel, etc. In application, it is
recommended to add parallel 33PF and 10PF capacitors to each power supply to effectively remove
high frequency interference.
