TPS77333DGKR Description

Short technical summary and product information.

The Texas Instruments TPS77333DGKR is a 250-mA low-dropout (LDO) voltage regulator designed for efficient power management. It provides a stable 3.3V fixed output voltage with a typical dropout voltage of 200 mV at 250 mA. The device features ultralow quiescent current of 92 µA at full load, making it suitable for power-sensitive applications.

 

Key features include fast transient response, thermal shutdown protection, and a 2% output voltage tolerance over specified conditions. The TPS77333DGKR is available in an 8-pin VSSOP package, suitable for surface mount applications. Its integrated power-on reset function (for TPS773xx family) adds system reliability.

 

This LDO regulator is optimized for stability with a wide range of output capacitors, including low ESR ceramic or low capacitance tantalum types. Its low noise performance of 55 µVrms without an external filter capacitor makes it ideal for noise-sensitive designs.
