SNAS512J september 2011 – may 2023 LMK00301
PRODUCTION DATA
For the LMK00301, when powering the VCC and VCCO pins from separate supply rails, it is recommended for the supplies to reach their regulation point at approximately the same time while ramping up, or reach ground potential at the same time while ramping down. Using simultaneous or ratiometric power supply sequencing prevents internal current flow from VCC to VCCO pins that could occur when VCC is powered before VCCO.
For the LMK00301A, there is no power supply sequencing requirement between VCC and VCCO.
