C1: Oscillation prevention capacitor (approx. 0.33µF)
Connection to terminal No.2 must be made as short as possible.
C2: Output capacitor (47 to 100µF)
Connection to terminal No.1 must be made as short as possible.
D1: Protection diode (RM1Z)
Required for protection against reverse biasing of input and
output.

C1
Note 1: Connect a 47µF to 100µF capacitor to both sides of the
load if the wiring between the output terminal and the
load is long.
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 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).
