That saves a component and a trace on the board. If your design expects an open-drain output for wired-OR sharing, this part will not work there — the push-pull stage fights any other driver. For a dedicated reset line to a single processor, it is the cleaner option. ## Sourcing and lifecycle reality Texas Instruments lists the LM809M3-4.63/NOPB as Active in production. For a BOM freeze or a long-production-run design, this is a low-risk line item.","metaTitle":"LM809M3-4.63/NOPB Simple Reset/Power-On Reset","metaDescription":"TI LM809M3-4.63/NOPB supervisor IC, active low reset, push-pull output, 140ms timeout, -40°C to 105°C, SOT-23-3.

The TLV803ED29DBZR is similar with a 33ms minimum timeout.
