TPS73618DCQR TI LDO Regulator | SOT-223-6 | 1.8V Output, 400mA

Product Overview

The TPS73618DCQR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed to deliver a fixed 1.8V output with a maximum current of 400mA. Housed in a compact SOT-223-6 package, this device offers excellent line and load regulation, making it suitable for noise-sensitive applications. The TPS73618DCQR features a low dropout voltage of typically 75mV at 400mA, enabling efficient operation even with small input-to-output voltage differentials. Its high power supply rejection ratio (PSRR) of 65dB at 1kHz ensures clean power delivery to sensitive loads.
