Note: 1) Large-value capacitors should be connected from pin 6 to ground right at the device
to provide a low impedance path! (appl. 1)
2) The use of plated through holes right at pin 2 and 5 is essential for pc-board-applications.
Thin boards are recommended to minimize the parasitic inductance to ground!
3) For more information please see application note 028 and 030.
