Voltage Regulators
AN77xxSP Series
3-pin, positive output, low dropout voltage regulator (1.2 A type)
AN77xxSP series
The AN77xxSP series is stabilized constant-voltage
power supplies with small difference between I/O voltages (0.5 V typ.). It is suitable for low-voltage, batterydriven equipment, and home appliances and industrial
equipment with great fluctuation of the supply voltage.
The output voltage ranges:
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 (■ Main Characteristics PD Ta).

■ Usage Notes
Not required
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 AN77xxSP 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 (pin 1) and the ground pin
(pin 2) of our conventional three-pin regulators
(AN78xxNSP series, etc.) were short-circuited at normal use conditions in some cases, the voltage of the
output pin (pin 3) 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 AN77xxSP 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)
