Luckily, the load for the way my NRF240 is set up is relatively low and stable so I managed to use a diode to drop the voltage. Thanks for the input guys!
Check very carefully.
Every time you switch between send/receive/standby the load will drop from about 14ma to about 1ma.
The voltage could rise a lot during those transitions if you're using a diode (and damage the chip).
