Hi，
I use LP87524B-Q1 to change 5V input to multi-outputs, including 3.3V,2.3V and 1.8V.
The 2,3V is used for radio module. The radio module transmit per 300ms and when transmission, it need current change 0A to 0.9A and the current last about 15ms.
Because of the load change, the 2,3V voltage drops about 40mVpp per 300ms, which also make the 5V input of LP87524B-Q1 drop and make the 1.8V output of LP87524B-Q1 also drop.
But the 1.8V output of LP87524B-Q1 is used to ADC as reference and it can't drop when the 2.3V drop.
What can I do to make the 1.8V stable when the 2.3V drop because of the load current change?
