Seeeduino Xiao 3.3v current source

For a lipo based project I need some current from the 3.3v regulator to feed some LEDs and the logic of a IRDA transceiver (not the IR diode).
How much current can I afford to draw from the 3.3V supply provided that there is a 3.7v battery on the 5V-pin?
Thanks and best regards

This is all the information we have about the voltage and current of the BLE.
