Linear & Switching Voltage Regulators

TPS7A4901DGNT Description

The TPS7A4901DGNT from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in demanding applications. With an adjustable output voltage range of 1.194V to 33V and a maximum input voltage of 35V, this regulator delivers up to 150mA of output current while maintaining exceptional efficiency. Its ultra-low dropout voltage of 0.6V at 150mA ensures stable operation even with tight input-output differentials. The device features a low quiescent current of 100 µA, making it ideal for battery-powered systems. Packaged in an 8-pin HVSSOP and available in tape & reel (TR), the TPS7A4901DGNT is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
