AN77xxSP Series
3-pin, positive output, low dropout voltage regulator (1.2 A type)
I Overview
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 AN77xxSP series

I 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.)

Note) *1: Expect for the operating ambient temperature and storage temperature, all ratings are for Ta = 25C. *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 150C (designed value). The relationship between the IC power dissipation and ambient temperature shall conform to the derating curve (I Main Characteristics PD Ta).

I Usage Notes
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. 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.

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)
