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
