• For the AN77L00/M series, the gain inside the IC is set high to improve the performance. For the reason, use the capacitor of 10µF or more when the power line in the output side should be long. In addition, install the capacitor in the output side as near as possible to the IC. AN77L00/M series V I V O 0.33µF 10µF n Application Circuit

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 µF 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.
