MOD5213 3.3V external loading

[Vernon]

I am building a project (quadcopter autopilot) using a MOD5213. I will power the module using 5V at PIN 40. I would like to operate a 74LVC245A level shifter (about 1 ma), a gyro accelerometer chip (4 ma), and a MAX3232 RS232 module (about 1MA but may have an LED). The regulator used on the MOD5213 module is nominally rated at 800 ma but I don't know how well it is heatsinked for external loads. How much load can be connected to the 3.3V output?

Thanks!

Running at 5V my concern would be dropout sag rather than temperature.
You are probably good to at least 150 ma additional.

Thanks - I will make sure the supply remains at 5V.
