* For MSOP-10 and USP-10B packages, please short the GND pins (pins 1 and 7).
*The dissipation pad for the USP-10B package should be solder-plated following the recommended mount pattern and metal masking
so as to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the
Ground pins (pins 1 and 7).
** For SOP-8 package, please short the GND pins (pins 1 and 5).
