The output is push-pull, totem pole, so it drives the reset line directly without needing an external pull-up resistor. That saves one component on the board — handy when you are packing a design into a tight SOT-23-3 footprint. The single-channel monitoring makes it a straightforward fit for any 3.3V rail that needs a clean, glitch-free reset signal. ## Active production and how to source it Sourced through independent distribution channels. ## How it compares to TL7702BID Both are simple reset/power-on reset supervisors, but the TL7702BID offers both Active High and Active Low outputs with an open-drain/open-collector stage, while the LM809M3X-3.08/NOPB is strictly Active Low push-pull.","metaTitle":"LM809M3X-3.08/NOPB Texas Instruments Simple Reset/Power-On","metaDescription":"Texas Instruments LM809M3X-3.08/NOPB Simple Reset/Power-On Reset, Active Low, Push-Pull output, 3.08V threshold, SOT-23-3.
