µF)

Connection to terminal No.3 must be made as short as

possible.

µF)

Connection to terminal No.2 must be made as short as

possible.

Required for protection against reverse biasing of input and

output.

Note 1: Prevention of oscillation at low temperatures

At low temperatures, oscillation may occur unless an

output capacitor with good tan

δ is used. Be sure to

connect a tantalum capacitor (approx. 10

µF) in paral-

Note 2: An isolation type diode is provided from input to ground

and also from output to ground. These may be de-

stroyed if the device is reverse biased. In this case,

Note 3: The output voltage may not be adjusted by raising the

ground voltage (using a diode or resistor).
