  • LM2842-Q1: Voltage regulation at FB pin is 0.803 V instead of specified 0.765 V, on recent production lot of 100 boards. Previous 1000 boards are at 0.765V as expected.

    Part Number: LM2842-Q1 We have used this part for 3 years now for a PCB in full production. In the latest fab run of boards, these devices seem to be regulating to a FB=0.803 V instead of FB=0.765. The timing of the regulator period is about 714 ns…
