Precautions on Use
1. Input Short-Circuit Protection Circuit
For the conventional Matsushita 3-pin regulators (such as
of the AN8000 series), when DC input pin3 is short-
circuited with GND w in the normal operation condition,
the potential of output pinq becomes higher than that of
DC input pin and the electric charges which is charged in
output capacitor C
O
flows in the input side, resulting in the
breakage of elements.
In the above case, the common silicon diode is connected
as shown in the right figure (the dotted line). However, for
the AN77L00/M series, since the protection circuit, which
protects the elements from the discharging current, is
incorporated in the internal circuit, the protection diode is
not required.
2. Capacitor for External Compensation
In order to secure the safety, the capacitor of 10
μ
F is
required in the output side and it should be added as near
as possible to output pin1 and GND 2. When it is used
under low temperature, oscillation may occur due to the
decrease of the aluminum electrolytic capacitor and
increase of ESR.
For the AN77L00/M, it is recommended that the tantalum
capacitor or aluminum electrolytic capacitor whose serial-
connected resistance equivalent with that of output
capacitor C
O
has temperature characteristics within the
recommended range specified in the right.
