The Texas Instruments TPS73643DBVT is a low-dropout (LDO) linear voltage regulator designed for portable and battery-powered equipment. It utilizes an NMOS pass transistor topology, providing stability with or without an output capacitor and offering excellent load transient response.
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 maximum output current of 400mA. The device exhibits low noise characteristics (30µVRMS) and high PSRR, making it suitable for noise-sensitive applications like VCOs. It also features thermal shutdown and current limit protection.
This regulator is available in a fixed 4.3V output version and comes in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package, ideal for space-constrained designs. Its low quiescent current, under 1µA in shutdown mode, further enhances its suitability for power-sensitive applications.
Applications include post-regulation for switching supplies, point-of-load regulation for DSPs, FPGAs, ASICs, and microprocessors, and general use in portable electronics.
