1.8V current sink for nRF52840

[ivnn]

Hi,
What is the maximum current capability of the 1.8V bus in this configuration?
The idea is to power external IC's from the 1.8V line
SYS - 5V usb

[Turbo J]

See PS chapter 5.3.8.2

Its 1mA in SYSTEM OFF, 5mA with full RADIO power and 25mA at reduced radio power output.
