That 2.64V trip point is set for a nominal 3.3V rail – it triggers when the supply drops about 20% below regulation, which is a common brownout detection window for 3.3V logic. If your processor needs a tighter threshold, this part will not work; but for a typical 3.3V MCU or FPGA bank, it is a standard fit. We source it per RFQ – confirm your BOM quantity and target delivery window, and we will quote against the current market pricing and lead time. ## Temperature grade and board-fit note","metaTitle":"TPS3809L30DBVR – TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3809L30DBVR supervisor IC – active low reset, push-pull output, 120ms timeout, 2.64V threshold.
