The Texas Instruments TPS73633DRBT is a high-accuracy, ultra-low-dropout linear voltage regulator designed for portable and battery-powered applications. Utilizing an NMOS pass transistor topology, it offers excellent load transient response and stable operation even without an output capacitor.
This regulator provides a fixed 3.3V output voltage with a maximum output current of 400mA. It accepts an input voltage range from 1.7V to 5.5V, with an ultra-low dropout voltage of typically 75mV at 400mA. Key electrical characteristics include low noise (30μVRMS typ), 0.5% initial accuracy, and 1% overall accuracy over line, load, and temperature variations. It also features less than 1μA maximum quiescent current in shutdown mode.
Protection features include thermal shutdown and foldback current limit, enhancing reliability. The TPS73633DRBT is available in an 8-SON (3x3) package, suitable for surface mount applications. Its design is ideal for noise-sensitive circuitry, post-regulation for switching supplies, and point-of-load regulation for processors.
Additional features include an Enable control input for power sequencing. The device offers robust performance with features like reverse current protection and excellent load transient response, making it a versatile choice for various power management needs.
