TPS7B8450QDCYRQ1M3 TI LDO Regulator | SOT-223-4 | 500mA, 50V, Low Quiescent Current

Product Overview

The TPS7B8450QDCYRQ1M3 is a high-voltage, low-dropout (LDO) linear regulator from Texas Instruments, designed for automotive and industrial applications. It delivers up to 500 mA output current with a wide input voltage range from 4V to 50V. The device features a low quiescent current of 15 µA (typical) and a dropout voltage of 300 mV at 500 mA. It is available in a SOT-223-4 package, making it suitable for space-constrained designs. The regulator offers fixed 5V output voltage with ±2% accuracy over temperature and load. Protection features include overcurrent, overtemperature, and reverse current protection.
