The Texas Instruments TPS73619DRBR is a low-dropout (LDO) linear voltage regulator designed for portable and battery-powered equipment. It utilizes an NMOS pass transistor topology, ensuring stability with or without an output capacitor and providing low reverse leakage current.
Key electrical specifications include an input voltage range of 1.7V to 5.5V, an ultra-low dropout voltage of 75mV typical at 400mA, and a fixed output voltage of 1.9V. The device can supply up to 400mA of current. It offers excellent load transient response and low noise performance (30µVRMS typical from 10Hz to 100kHz). Accuracy is 0.5% initial and 1% overall over line, load, and temperature.
Protection features include thermal shutdown and current limiting. The quiescent current is less than 1µA in shutdown mode, making it suitable for power-sensitive applications. The regulator is available in an 8-SON (3x3) package, designed for surface mounting.
Applications include post-regulation for switching supplies, noise-sensitive circuitry like VCOs, and point-of-load regulation for DSPs, FPGAs, ASICs, and microprocessors.
