TPS79618DCQRG4 TI LDO Regulator | SOT-223-6 | 1A, 1.8V Output

Product Overview

The TPS79618DCQRG4 from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver up to 1A of output current with a fixed output voltage of 1.8V. Housed in a compact SOT-223-6 package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. With a dropout voltage of typically 240mV at full load, it ensures efficient operation even with low input-to-output voltage differentials. The TPS79618DCQRG4 integrates a low-noise bandgap reference, current limit, and thermal shutdown protection, providing a robust power management solution for modern electronic systems.
