Additional Details

The APL5102-35DI-TRL operates with a fixed output voltage of 3.5V. It is available in a small surface-mount package (e.g., SOT-25 or similar). The regulator's low dropout voltage allows it to maintain regulation even when the input voltage drops close to 3.5V, making it suitable for battery-powered applications where the battery voltage decreases over time. The device also includes internal protection features such as current limiting and thermal shutdown to prevent damage from overloads or excessive heat. Detailed specifications including input voltage range, output current capability, dropout voltage characteristics, and thermal resistance are typically available in the product datasheet.
