Can I power my whole circuit with the internal USB Voltage Regulator (VOUT33)?

[m4l490n]

If I have a simple device consisting of an MK22FX512AVLH12 and other small devices whose total consumption is not more than 100ma, could I power the whole board using the internal USB voltage regulator (Vout33)?

That would mean connecting the VOUT33 to the K22 VDD which doesn't sound right but I'm not sure.

Anyway, is this possible?

Hi m4l490n,

  Please check the datasheet:

So, your consumption is below 100mA, you can use the VOUT to power on the 3v3, it's OK.

Wish it helps you!
