TPS74901RGWR Part Information

Details for TPS74901RGWR by Texas Instruments

Semiconductors - ICs>Power Management ICs - PMIC>Voltage Regulators

Part Description

The TPS74901 low-dropout (LDO) linear regulator provides an easy-to-use, robust power management solution for a wide variety of applications. Userprogrammable soft-start minimizes stress on the input power source by reducing capacitive inrush current during start-up. The soft-start is monotonic and wellsuited for powering many different types of processors and ASICs. The enable input and powergood output allow easy sequencing with external regulators. This complete flexibility permits the user to configure a solution that meets the sequencing requirements of FPGAs, DSPs, and other applications with special start-up requirements. A precision reference and error amplifier deliver 2% accuracy over load, line, temperature, and process. The device is stable with any type of capacitor ≥ 2.2 µF, and the device is fully specified from –40°C to 125°C. The TPS74901 is offered in a small (3 mm × 3 mm) VSON package and a small (5-mm × 5-mm) VQFN package, yielding a highly compact total solution size. The device is also available in a DDPAK-7 package.
