We found a new problem from our mass production automotive front-view camera. In the circuit design we selected LP5907QMFX-2.8Q1 to supply AVDD voltage of the
image sensor IC. But on the fail products the output voltage of LP5907QMFX-2.8Q1 is drop down to 2.6V. We trid to improve the Vin up to 4.5V, also cut off the load
circuit, and the LDO still cannot output the correct voltage(2.8V). The problem can't be solved until we replace it with a new IC. My question what factors can cause this
issue? And how to avoid it? Thanks a lot!
