AN7700, AN7700F, AN7700SP Series
Low-dropout three-pin voltage regulator 1.2-A type
n Overview
The AN7700, AN7700F, and AN7700SP series are
stabilized constant-voltage power supplies with small dif-
ference between I/O voltages (0.5 V typ.). They are suit-
able for low-voltage, battery-driven equipment, and home
appliances and industrial equipment with great fluctua-
tion 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
n 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.)
n Applications
• Power supply equipment
