The TLV803EA29VDBZR is a simple reset/power-on supervisor that monitors a single voltage rail and holds the reset output active-low until the supply has been above the threshold for the full timeout period.
The SOT-23-3 package is a standard three-pin footprint that hand-solders easily and fits tight layouts. Surface-mount only — no through-hole variant.
The TLV803ED29DBZR is a functional equivalent with the same 2.9V threshold and SOT-23-3 package, but its minimum reset timeout is 33ms instead of 130ms. Verify your system's required reset hold time before substituting.
Yes, the 2.9V threshold is designed for a 3.3V supply rail. It asserts reset when the voltage falls below 2.9V, providing a clean brown-out and power-up reset signal.
The minimum reset timeout is 130ms. The output stays low for at least that duration after the supply rises above the 2.9V threshold.
Active low. The reset output goes low when the monitored voltage drops below the threshold and stays low through the timeout period.
