Note 1: Vcc down to 0.5V may be used for backed-off power when using DC/DC converter to reduce low power current drain. Refer to Look-up Table (LUT, supplied

separately) for recommended Vcc settings for each output power level.

Note 2: Device in Power Down Mode, VIO = 1.8V, Vbatt = 3.0V, Vcc = 2.5V.
