Overview of TPS7A4501KTTR

The TPS7A4501KTTR is a low-dropout (LDO) voltage regulator from Texas Instruments designed for high-performance applications that require very low noise and high-PSRR. It has a 36-V input voltage range, making it suitable for various industrial and automotive systems. The device offers a low typical dropout voltage of 250mV at 1A load, ensuring efficient power delivery even in the presence of small voltage differentials.The TPS7A4501KTTR features a fast start-up time of less than 100μs, enabling quick power delivery to sensitive components. It also has a low quiescent current of less than 100μA, ensuring minimal power consumption when the regulator is idle. The device has an adjustable output voltage range from 0.6V to 36V, allowing for flexibility in system design.In addition, the TPS7A4501KTTR is offered in a small, thermally-enhanced 20-pin VQFN package, making it easy to integrate into space-constrained applications.
