TPS7B4256QDDARQ1 TI LDO Regulator | 8-SO-POWERPAD | 40V, 300mA

Product Overview

The TPS7B4256QDDARQ1 is a high-voltage, low-dropout (LDO) linear regulator from Texas Instruments, designed for automotive and industrial applications. It operates from an input voltage range of 3V to 40V and delivers up to 300mA of output current with a typical dropout voltage of 300mV at full load. The device features a fixed output voltage of 5V, with an accuracy of ±2% over line, load, and temperature variations. It is housed in an 8-pin SO PowerPAD package, which enhances thermal dissipation for reliable operation in harsh environments.
