[Paparazzi-devel] Switching Regulator

Paparazzi Community,

The TI switching regulator found on the Tiny architecture has a maximum rated current draw of 2.25 A, and the wiki says that you can power external devices and sensors requiring 5v through it. However I have seen posts which do not recommend placing additional external loads on the regulator. What is the safety margin for powering devices through the regulator? If you were required to power a number of loads externally with a draw of 0.8-1.2 A what small, lightweight regulators would you suggest?

Thank you for your feedback!
