AS7809ADTR-E1 Description

Short technical summary and product information.

The AS7809ADTR-E1 from Diodes Incorporated is a three-terminal positive voltage regulator designed for various applications requiring stable voltage regulation. It offers a fixed output voltage of 9V and can deliver an output current of up to 1A, provided adequate heat sinking is used.

 

Key electrical features include a maximum input voltage of 29V, a typical voltage dropout of 2V at 1A, and internal protection mechanisms such as short-circuit current limiting and thermal overload protection. The device also includes safe-area compensation for the output transistor.

 

This regulator is housed in a TO-252-3 (DPAK) surface-mount package, making it suitable for space-constrained designs. It operates across a wide temperature range of -40°C to 125°C, ensuring reliable performance in demanding environments. The AS78XXA series, to which this part belongs, is designed for applications like local on-card regulation, post-regulation for switching supplies, and power supplies for microprocessors and motherboards.
