with Vo1 (single output power
supply) by selecting NC (open) for
5Pin:Vc, 6Pin:Vin2 and 7Pin: Vo2.
Notes: *1: With glass epoxy + copper foil board (size 5.0 • 7.4cm; t: glass epoxy = 1.6mm / copper foil = 18µm)

Tantalum capacitors are recommended particularly for low
temperatures (tantalum capacitors of about 0.47µ F in parallel).
D1, D2: Protection diodes.
Required for protection against reverse biasing between input
and output (Recommended diode: SANKEN EU2Z).
