TPS7A4450DGQR TI LDO Regulator | 10-HVSSOP | 50V, 150mA, Low Noise

Product Overview

The TPS7A4450DGQR is a high-voltage, low-dropout (LDO) linear regulator from Texas Instruments, designed for applications requiring a wide input voltage range up to 50V. It delivers up to 150mA of output current with excellent line and load transient response. The device features a low dropout voltage of typically 300mV at full load, making it suitable for powering sensitive analog and digital circuits. The TPS7A4450DGQR is available in a compact 10-pin HVSSOP package, ideal for space-constrained designs.
