Voltage Regulators

AN7700, AN7700F, AN7700SP Series

■ 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 condi-

tions in some cases, the voltage of the output pin (pin3)

becomes higher than that of the DC input pin and elec-

trons charged in the output capacitor C_OUTflow 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 be-

cause 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 elec-

trolytic capacitor and increase of ESR of this capacitor

may lead to oscillation.

In the AN7700/AN7700F/AN7700SP series, for the

output capacitor C_OUT, it is recommended to use an

aluminum electrolytic capacitor or tantalum capacitor

whose equivalent series resistance (ESR) has the tem-

perature characteristic within the recommended area

shown on the right.

6 V to 16 V

1) The overvoltage protection is activated with the ASO

protection circuit when V_IN= 30 V is applied, and

the output shuts down occasionally. (3-V type to

10-V type)

7 V to 17 V

8 V to 18 V

9 V to 19 V

10 V to 20 V

11 V to 21 V

13 V to 23 V

16.5 V to 26.5 V

19.5 V to 29.5 V

21.5 V to 29.5 V

25.5 V to 29.5 V

2) Please note that at I_OUT< 2 mA, the output voltage

rises and may exceed the maximum of the operation

range. (12-V type to 24-V type)
