The TPS73618DBVRG4 is a low-dropout (LDO) linear voltage regulator designed for applications requiring stable output without the need for an output capacitor. It operates within an input voltage range of 1.7V to 5.5V and features an ultra-low dropout voltage of 75mV typical. The device is capable of delivering up to 400mA of output current and offers excellent load transient response, making it suitable for noise-sensitive applications such as voltage-controlled oscillators (VCOs) and point-of-load regulation for digital signal processors (DSPs), field-programmable gate arrays (FPGAs), and microprocessors. This regulator utilizes an NMOS topology, which minimizes reverse leakage current and maintains low ground pin current across various output currents. It boasts a low output noise of 30OºV RMS (10Hz to 100kHz) and provides high precision with 0.5% initial accuracy and 1% overall accuracy across line, load, and temperature variations. The TPS73618DBVRG4 also includes thermal shutdown and current limit protection features, ensuring safe operation. It is available in a compact SOT-23 package, making it suitable for space-constrained designs.
