The Texas Instruments TPS73633DCQR is a high-accuracy, ultra-low-dropout linear voltage regulator designed for portable and battery-powered applications. It features an NMOS pass transistor topology, enabling stability with or without an output capacitor and providing 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 (10Hz to 100kHz), and excellent load transient response. It also offers 0.5% initial accuracy and 1% overall accuracy over line, load, and temperature variations.
Protection features include thermal shutdown and current limit protection. The device consumes less than 1µA in shutdown mode, making it suitable for power-sensitive designs. It is supplied in a SOT-223-6 surface-mount package.
Applications include post-regulation for switching supplies, noise-sensitive circuitry like VCOs, and point-of-load regulation for DSPs, FPGAs, ASICs, and microprocessors.
