The Texas Instruments TPS74901KTWR is a high-performance, 3A adjustable ultra-low-dropout linear voltage regulator designed for various power management applications. It offers a wide input voltage range from 0.8V to 5.5V and an adjustable output voltage range from 0.8V to 3.6V.
Key electrical characteristics include a low dropout voltage of 120mV at 3A, a typical quiescent current of 3mA, and a PSRR of 28dB at 100 KHz. The regulator is stable with any output capacitor greater than or equal to 2.2µF. It provides essential control features such as Enable, Power Good output for supply monitoring or sequencing, and programmable Soft Start for in-rush current control.
This device is available in multiple packages including DDPAK/TO-263-7, VSON (3mm x 3mm), and VQFN (5mm x 5mm), supporting surface mount applications. The operating temperature range is -40°C to 125°C, making it suitable for demanding environments. Protection features include over current, over temperature, short circuit, and under voltage lockout (UVLO).
The TPS74901KTWR is ideal for applications requiring a stable and efficient power supply with tight regulation and low noise. Its adjustable output and comprehensive protection features make it a versatile choice for power system designs.
