µF)

Connection to terminal No.1 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 par-

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

ground and also from output to ground. These may

be destroyed if the device is reverse biased. In this
