Technical Specifications

The AP1084D25 is a 3A low dropout positive regulator with a fixed output voltage of 2.5V. It features a typical dropout voltage of 1.3V at the full rated current of 3A. This means that the regulator can maintain a stable 2.5V output even when the input voltage drops to only 3.8V. The device is designed with internal current limiting and thermal shutdown circuitry to protect it from overloads and excessive heat. The regulator is available in both TO-252 (D-PAK) and TO-263 (D2-PAK) packages, allowing for flexible mounting options based on thermal and space requirements. It provides excellent line and load regulation, ensuring a stable output voltage under varying input voltage and load conditions. It is well-suited for applications requiring a regulated 2.5V supply with high current capability, such as powering microcontrollers, memory devices, and other sensitive electronic components.

This voltage regulator is designed to provide reliable and efficient power management in a variety of electronic systems, ensuring stable operation and protection against potential faults.
