AT7140 DESCRIPTION
The AMC7140 is a high voltage, low dropout current regulator. The output current can be programmed by an external resistor which sets the full
scale LED string current up to 700mA and the output sink current could be disabled via OE pin. Additional feature includes thermal protection function to ensure the system reliability. Therefore, a large amount of current can be handled safely in one package. The device is available in TO-252-5L package.
