Capacitor for external compensation To maintain the stability, insert a 33-mF capacitor as close to pin 3 and pin 2 as possible. In case of using at low temperature, decrease in capacity of the aluminum electrolytic capacitor and increase of ESR of this capacitor may lead to oscillation. In the AN7700/AN7700F/AN7700SP series, for the output capacitor COUT , it is recommended to use an aluminum electrolytic capacitor or tantalum capacitor whose equivalent series resistance (ESR) has the temperature characteristic within the recommended area shown on the right. Not required 3 1 VIN VOUT COUT 33 µF 2 CIN 0.33 µF Output capacitor ESR (Equivalent series resistance) Ta = 25°C 10 000 VIN = Refer to the table below. IOUT = 0 A to 1 A COUT = 33 µF 1 000 100 ESR (Ω) 1. Input short-circuit protection circuit When the DC input pin (pin1) and the ground pin (pin2) of our conventional three-pin regulators (AN7800 series, etc.) were short-circuited at normal use conditions in some cases, the voltage of the output pin (pin3) becomes higher than that of the DC input pin and electrons charged in the output capacitor COUT flow into the input side, resulting in break of the element. In those cases, it was necessary for you to connect a general silicon diode as shown in the figure on the right. In the AN7700/AN7700F/AN7700SP series, however, it is not necessary to connect the protection diode because these series have a built-in protection circuit to safeguard the element from discharge current. 10 Ω (typ.) 10 Usable range 1.0 0.1 1 CIN 0.33 µF 2 VIN 3 IOUT COUT 33 µF ESR GND 3.
