Characteristics
I
Standard External Circuit
C
1
: Oscillation prevention capacitor (approx. 0.33
μ
F)
Connection to terminal No.4 must be made as short as
possible.
C
2
: Output capacitor (47 to 100
μ
F)
Connection to terminal No.1 must be made as short as
possible.
D
1
: 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 tan
δ
is used. Be sure to
connect a tantalum capacitor (approx. 10
μ
F) in par-
allel with output capacitor C
2
.
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 V
F
to protect them.
