Condition / Note
When enabled
Voltage regulator already enabled
New toggle voltage programmed
May be software calibrated for
known reference voltage
Regulated 1.8 V supply voltage
generated by on-chip voltage
regulator.
Regulated 1.8 V supply voltage
generated by on-chip voltage
regulator. The digital I/O voltage
(DVDD3.3 pin) must match the
external interfacing circuit (e.g.
microcontroller).
Current drawn from VREG_IN,
through voltage regulator
Voltage regulator off
Voltage regulator on
Including voltage regulator
The output power is delivered
differentially to a 50 Ω singled
ended load through a balun, see
also page 52.
