q Wiring condition is very important. Noise associated with wiring inductance may cause some problems.
w When output voltage is not stable, it can be improved by attaching capacitor (from several nF to several dozens nF) to
For minimizing inductance, it is recommended to design the thick and short pattern (between large current diodes,
input/output capacitors, and terminal 1, 2. Single-point grounding (as indicated) should be used for best results.
