■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
