I have a TPS50601 design that appears to losing regulation. It is a +3.3V input to +1.2V output. The +1.2V falls at which point our +1.0V brown-out circuit kicks in, removes the load, which causes the output to recover. The +1.2V is operating well within the load range as the +3.3V input current is ~850mA. Can you provide guidance? Thank you!
