*The dissipation pad for the USP-6C package

should be solder-plated in 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 pin No.1.

FUNCTIONS

: Ground

: Output Voltage Montior, Internal Power Supply
