DRIVE AN POWER AMPLIFIER USING GPIO PIN

Hi Nordic.

Now I am working on a BLE smart card and am adding an external power amplifier. For low power consumption, i decided to give power only when I want PCB doesn't allow me to add more switching components so I think its a good idea to provide power via GPIOpins .my power amplifier is sky66111 and it needs 11mA to work. can I drive a power amplifier via  GPIO pin.?

Please replay.
