Hi to all,
actually we’ve got one issue with the LDO TPS7A8300RGR.
On our desk we’ve got two identical circuit boards with the LDO TPS7A8300 on it.
Because the two boards have different output voltages at the LDO, we checked the circuit around the LDO carefully.
By checking the LDO itself, we recognized, that there is a different labeling on the chips.
LDO_1:
PA9Q
TI 71|
AXEO
LDO_2:
PA9Q
TI 72|
COPV
So are both chips really the TPS7A8300? Or do we have there different voltage regulators?
What is the reason for the different labeling? Different chip versions?
Thank you very much for your support.
Best regards,
Paul Rott
