Hello E2E,
Our customer is using the LP2951 for mass production product. The output voltage of the LP2951 used in that product had dropped over time.
Initial Voltage : 5.018V
After 4000 hours : 5.007V
Customers want to know the reason for that.
I know that the bandgap Vref has aging characteristics.
Q1
: Does TI have data for internal bandgap aging of LDO?
Q2
: Please let me know why internal bandgap has error by long term aging.
Regards,
ACGUY
