Voltage Regulators
AN7700, AN7700F, AN7700SP Series
Low-dropout three-pin voltage regulator 1.2-A type
AN7700 series
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

• 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.)

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 (■ Characteristic curve chart PD  Ta).

■ Usage Notes
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.

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.

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)
