Usage Notes
1. Cautions for a basic circuit
C
I
: When a wiring from a smoothing circuit to a three-pin regulator
is long, it is likely to oscillate at output. A capacitor of 0.1
μ
F to
0.47
μ
F should be connected near an input pin.
C
O
: Deadly needed to prevent from oscillation (0.33
μ
F to 1.0
μ
F). It
is recommended to use a capacitor of a small internal imped-
ance (ex. tantalum capacitor) when using it under a low tem-
perature.
When any sudden change of load current is likely to occur, con-
nect an electrolytic capacitor of 10
μ
F to 100
μ
F to improve a
transitional response of output voltage.
D
i
: Normally unnecessary. But add it in the case that there is a
residual voltage at the output capacitor Co even after switching
off the supply power because a current is likely to flow into an
output pin of the IC and damage the IC.
