2.64V threshold supervisor in SOT-23-5 — what it locks and where it sits
Texas Instruments TPS3836L30DBVT is a single-channel voltage supervisor that asserts a reset when the monitored supply drops below 2.64V. The active-low, push-pull output means the reset signal goes low on fault and stays low for a minimum 10ms timeout after the supply recovers. No external pull-up resistor is needed — the totem-pole stage drives high or low directly, saving one component per rail. The SOT-23-5 package is a standard supervisor footprint that drops onto existing PCB layouts without a board revision.
Push-pull vs open-drain — BOM simplification on the reset line
Unlike the TLV803ED29DBZR, which uses an open-drain output and requires a pull-up resistor to the supply rail, the TPS3836L30DBVT's push-pull output eliminates that external component. For a 3.0V rail with a 2.64V threshold, the push-pull stage drives the reset pin directly to the rail voltage, saving a resistor and one assembly pick.
