Overview
Voltage Regulators AN7700, AN7700F, AN7700SP Series Low-dropout three-pin voltage regulator 1.
2-A type s 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.
