TLV803SDBZR

TLV803SDBZR is the S variant of a three-pin voltage supervisor in a SOT-23-3 (DBZ) package, monitoring with a 2.93 V threshold and asserting an active-low open-drain reset for a fixed 200 ms after the rail recovers. It works from a 1.1 V to 6 V supply and is rated from -40 C to +125 C. With only three pins and no timing components to place, it adds dependable power-on and brownout reset to cost-sensitive designs, protecting microcontrollers and DSPs from running below their specified voltage and corrupting memory or I/O states. Selection advice: the S code fixes the 2.93 V threshold, which suits nominal 3.3 V rails; check that 2.93 V sits safely below your rail tolerance and above the load's minimum operating voltage, and choose a different threshold code in the family if it does not. The DBZR suffix is the tape-and-reel SOT-23-3 code to quote. Parameters verified against Texas Instruments documentation.
