Technical Specifications

The AMC7135 typically supports an input voltage range of 2.7V to 6V and can deliver a constant output current of up to 350mA. It is available in various packages, such as SOT-89. The dropout voltage is typically low, allowing the LED to be driven even when the battery voltage is close to the LED's forward voltage. The thermal protection feature prevents the device from overheating by reducing the output current when the temperature exceeds a certain threshold.
