Hi–Fi equipment and active loudspeakers can be realized as well as applications in TV receivers and
video recorders.
Features:
D Wide Operational Range
D High Voltage Stability Even at High Load Changes
D Direct Control of Switching Transistor
D Low Start–Up Current
D Linear Foldback of the Overload Characteristic
D Base Drive Proportional to the Current Through the Power Switching Transistor
D Stand–By Mode 3.5W into the External Load
D Inhibit Capability (TTL Compatible)
D Undervoltage Lockout
