In a multi-rail system, this window allows downstream regulators to reach regulation before the core boots, preventing brown-out or undefined start-up states.","metaTitle":"TPS3851G33EQDRBRQ1 Simple Reset/Power-On Reset, AEC-Q100","metaDescription":"Texas Instruments TPS3851G33EQDRBRQ1 Simple Reset/Power-On Reset IC.
