TLV75733PDBVR

TLV75733PDBVR is the tape-and-reel SOT-23-5 ordering code for the Texas Instruments TLV757P low-dropout regulator, fixed 3.3 V output variant, listed by TI as Active. It accepts a 1.45 V to 5.5 V input, holds accuracy within -1 % to +1 % over a -40 °C to +85 °C junction range (±1.5 % over the full temperature range), and its dropout is 300 mV typical and 425 mV maximum at a 1 A load over -40 °C to +85 °C, with the full-temperature maximum at 475 mV under the same load; the current limit sits between 1.2 A and 1.78 A (1.55 A typical). The selection point is a full 1 A of regulated 3.3 V from a five-pin package: post-regulation after a buck stage, point-of-load rails for radios and processors, and retrofits where board area rules out larger regulator packages. Selection advice: the 33 code is the fixed 3.3 V member of the TLV757P family - other voltage codes share the footprint, so confirm the code against the rail voltage; and design the input headroom against the 425 mV dropout maximum at temperature, not the typical figure, if the rail must hold regulation at a 1 A load. Parameters verified against the TI TLV757P datasheet (ordering appendix and electrical characteristics).
