nrf51 QFN LDO Ref Design L2 value

[Oleh]

I've noticed that the L2 value has been changed from 10nH to 27nH in the reference layout and on the new boards (DK and Dongle). This value is only for LDO setup (from PS ver 3.1)

Can you please share some more details? What will be the impact when used the old value?

Thank you!

The L2 = 27 nH is in the product specification for all the QFACxx version of nRF51. This is slightly different from the previous AA and AB versions and hence needed some additional inductance to handle receiver local oscillator leakage. So only use 27 nH along with the QFACxx version.

Thank you, Asbjørn! :-)
