概述
Description
TLV70733PDQNR is a fixed-output low-dropout regulator (LDO) from TI’s TLV707 family. It provides a regulated 3.3 V output from a higher input voltage, making it suitable for compact, battery-powered electronics that need a clean 3.3 V rail. The device emphasizes ultra-low quiescent current, fast transient response, and built‑in protections (short-circuit protection, thermal shutdown, current limit). It includes an enable (EN) input to shut the regulator off for power saving.
The part is offered in TI’s compact PDQ package (PDQNR), enabling small-footprint designs. Typical applications include microcontroller peripherals, sensors, wireless devices, and any application requiring a stable 3.3 V supply.
Usage notes: use the recommended input and output capacitors close to the regulator to ensure stability; drive EN to enable or disable the device; stay within the specified input range and thermal limits.
For exact electrical specs and packaging details, refer to the TLV70733 datasheet on TI’s website.
