TPS73718DCQR TI LDO Regulator | SOT-223-6 | 1A, 1.8V Fixed Output

Product Overview

The TPS73718DCQR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for applications requiring high accuracy and low noise. With a fixed output voltage of 1.8V and a maximum output current of 1A, it offers excellent line and load regulation. The device operates over a wide input voltage range from 2.7V to 5.5V, making it suitable for battery-powered and industrial systems. Its low dropout voltage of typically 130mV at 1A ensures efficient operation even with small input-to-output voltage differentials. The TPS73718DCQR is available in a compact SOT-223-6 package, ideal for space-constrained designs.
