C1: Oscillation prevention capacitor (approx. 0.33µF)
Connection to terminal No.3 must be made as short as
possible.
C2: Output capacitor (47 to 100µF)
Connection to terminal No.2 must be made as short as
possible.
D1: Protection diode (RM1Z)
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 tanδ is used. Be sure to
connect a tantalum capacitor (approx. 10µF) in paral-
lel with output capacitor C2.
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,
use a diode with low VF to protect them.
Note 3: The output voltage may not be adjusted by raising the
ground voltage (using a diode or resistor).
