Optional bias pin for the RF LNA
1.8 V to 3.8 V main chip supply⁽¹⁾
1.8 V to 3.8 V GPIO supply⁽¹⁾
1.8 V to 3.8 V DC/DC supply. Tie to ground for external
regulator mode (1.7 V to 1.95 V operation)
1.7 V to 1.95 V supply, typically connect to output of internal
DC/DC ^{(2) (3)}
1.7 V to 1.95 V supply, typically connect to output of internal
DC/DC ^{(4) (3)}
1.27 V regulated digital-supply decoupling capacitor⁽³⁾
Ground
(1) See Section 8.2, technical reference manual for more details.
(2) If internal DC/DC is not used, this pin is supplied internally from the main LDO.
(3) Do not supply external circuitry from this pin.
(4) If internal DC/DC is not used, this pin must be connected to VDDR for supply from the main LDO.
