nRF51822: Internal 1.8V LDO - output current capability

[Nick]

Can the nRF51822 DEC2 pin (LDO output) be used as a 1.8V supply for low current use (say, <50uA)? Similarly, how about the 1.9V output of the buck converter (AVdd)? The current capabilities of these two outputs aren't really documented (I guess they aren't expected to be used this way).

Cheers :)

The chip and this output has not been designed for this, and we haven't done any tests or verification of it, so I can not recommend it. It could be that it works, but you will be on your own if you chose to do it. Sorry for the inconvenience.

To follow up, did you end up successfully using the DEC2 pin LDO output as a 1.8V supply for external components that require low current? I also think it would be very useful to be able to use this, so I'd love to know if you tried it! ~Jackie

Hey Jackie,

Apologies for the late reply - I actually didn't end up requiring it. Did you try it in the end?

This thread was posted a while ago, have there been any tests of updates since then?
