The Texas Instruments TPS73218DBVT is a low-dropout (LDO) linear voltage regulator designed for portable and battery-powered applications. It provides a stable 1.8V output at up to 250mA with an input voltage range of 1.7V to 5.5V.
This NMOS-based regulator is notable for its stability with no output capacitor or any type of capacitor, and it exhibits excellent load transient response. Key electrical characteristics include ultra-low dropout voltage (40mV typical at 250mA), low noise (30µVRMS typical), and high accuracy (0.5% initial, 1% overall).
The device consumes less than 1µA in shutdown mode, making it ideal for power-sensitive designs. It also includes thermal shutdown and current limit protection features. The TPS73218DBVT is supplied in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package.
Applications include post-regulation for switching supplies, noise-sensitive circuitry like VCOs, and point-of-load regulation for DSPs, FPGAs, and microprocessors.
