Additional Details

The ADP3338AKC33REEL typically operates with an input voltage range of 2.5 V to 12 V, and it provides a fixed output voltage of 3.3 V. The low dropout voltage allows it to maintain regulation even when the input voltage is close to the output voltage, making it suitable for battery-powered applications. The regulator also features internal current limiting and thermal shutdown protection to prevent damage from overload conditions. The shutdown function allows the regulator to be turned off externally, further reducing power consumption when the device is not in use. It is available in a small TSOT package, making it suitable for space-constrained applications. The ADP3338 is designed to provide a cost-effective and efficient solution for a wide range of voltage regulation requirements.
