CP
LEGEND A = Analog, I = Input, O = Output, OH = 5 mA High Output Drive, R = Regulated Output.
Pin
No.
3. The center pad (CP) on the QFN package must be connected to ground (Vss) for best mechanical, thermal, and electrical performance. If not connected to ground, it
must be electrically floated and not connected to any other signal.
