What are the key specifications?

It provides a 5.0 V fixed output, supports up to 1.0 A output current, has a 1.2 V maximum dropout at 800 mA, and operates with input voltages up to 20 V.

What should be considered for thermal management?

The device features internal thermal shutdown. Proper heatsinking using PCB copper area is required to maintain the junction temperature within safe limits.

What are the stability requirements?

A minimum output capacitance of 4.7 µF with an ESR between 33 mΩ and 2.2 Ω is mandatory to ensure regulator stability.
