AN7700, AN7700F, AN7700SP Series
Low-dropout three-pin voltage regulator 1.2-A type
s Overview
The AN7700, AN7700F, and AN7700SP series are stabilized constant-voltage power supplies with small difference between I/O voltages (0.5 V typ.). They are suitable for low-voltage, battery-driven equipment, and home appliances and industrial equipment with great fluctuation of the supply voltage. The output voltage ranges: For AN7700, AN7700F 3 V, 4 V, 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V, 20 V, and 24 V For AN7700SP 3.3 V, 3.5 V, 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, and 15 V AN7700 series

Note) *1: Expect for the operating ambient temperature, and storage temperature, all ratings are for Ta = 25°C. *2: At the application of VIN = 30 V, the overvoltage protection may be operated by the ASO protection circuit, leading to the output shut down. *3: The current value does not exceed this criterion because of the on-chip current limiter. *4: The internal circuit shuts off the output when Tj ≥ 150°C (designed value). The relationship between the IC power dissipation and ambient temperature shall conform to the derating curve (s Characteristic curve chart PD Ta).

s Usage Notes
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. 2. 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.

3. Others Cautions for the input voltage that exceeds the operating supply voltage: 1) The overvoltage protection is activated with the ASO protection circuit when VIN = 30 V is applied, and the output shuts down occasionally. (3-V type to 10-V type) 2) Please note that at IOUT < 2 mA, the output voltage rises and may exceed the maximum of the operation range. (12-V type to 24-V type)
