AN7700, AN7700F, AN7700SP Series

Low-dropout three-pin voltage regulator 1.2-A type

■ 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

■ Features

• Minimum I/O voltage difference: 0.5 V (typ.)

• On-chip overcurrent limiter

• On-chip thermal protection circuit

• On-chip inrush current protection circuit at the time of

input voltage start-up

• On-chip input short-circuit protection circuit

(When the input pin is short-circuited to the ground, the
circuit between pins 1 and 3 is shut down to prevent
current flow.)

■ Applications

• Power supply equipment

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

■ 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 C

flow into the

OUT

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 C

, it is recommended to use an

OUT

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 V

= 30 V is applied, and

IN

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

10-V type)

2) Please note that at
