TPS73633DRBR Description

Short technical summary and product information.

The Texas Instruments TPS73633DRBR is a high-accuracy, ultra-low-dropout linear voltage regulator designed for portable and battery-powered applications. It features an NMOS pass transistor topology, providing stable operation with or without an output capacitor and offering low reverse leakage current.

 

This regulator operates with an input voltage range of 1.7V to 5.5V and delivers a fixed 3.3V output at up to 400mA. Key electrical characteristics include an ultra-low dropout voltage of 75mV typical, low noise of 30µVRMS, and 1% overall accuracy over line, load, and temperature. It also includes features like thermal shutdown and foldback current limit protection.

 

The TPS73633DRBR is available in an 8-SON (3x3) package, suitable for surface mount applications. Its low quiescent current (under 1µA in shutdown mode) and robust protection features make it a reliable choice for noise-sensitive circuitry, post-regulation for switching supplies, and point-of-load regulation for processors.

 

Applications include portable and battery-powered equipment, post-regulation for switching supplies, noise-sensitive circuitry such as VCOs, and point-of-load regulation for DSPs, FPGAs, ASICs, and microprocessors.
