The TPS793xx family of low-dropout (LDO) low-power linear voltage regulators features high power-supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses in NanoStar wafer chip scale and SOT23 packages. NanoStar packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making it ideal for portable devices and wireless communication applications.
The TPS793xx family comprises ultra‑low‑noise, high‑PSRR 200 mA low‑dropout linear regulators offered in fixed and adjustable output versions. They are targeted at portable RF, audio, cellular, Bluetooth, and handheld applications where low noise and fast start‑up are critical.
The datasheet provides full electrical characteristics, absolute maximum ratings, package options (5‑ and 6‑pin SOT23 (DBV) and NanoStar wafer‑scale (YEQ)), thermal and dissipation data, as well as mechanical drawings and handling precautions.
