Kynix-PMIC - Voltage Regulators - Linear-TPS74401KTWR

FEATURES
Soft-Start (SS) Pin Provides a Linear Startup with Ramp Time Set by External Capacitor 1% Accuracy Over Line, Load, and Temperature Supports Input Voltages as Low as 0.9V with External Bias Supply Adjustable Output to 3.6V) Ultra-Low Dropout: at 3.0A (typ) Stable with Any or No Output Capacitor Excellent Transient Response Available × 1mm QFN and DDPAK-7 Packages Open-Drain Power-Good (QFN only) Active High Enable

DESCRIPTION
The TPS74401 low-dropout (LDO) linear regulator provides an easy-to-use robust power management solution for a wide variety of applications. User-programmable soft-start minimizes stress on the input power source by reducing capacitive inrush current on start-up. The soft-start is monotonic and well-suited for powering many different types of processors and ASICs. The enable input and power-good output allow easy sequencing with external regulators. This complete flexibility permits the user to configure a solution that will meet the sequencing requirements of FPGAs, DSPs, and other applications with specific start-up requirements. A precision reference and error amplifier deliver 1% accuracy over load, line, temperature, and process. Each LDO is stable with low-cost ceramic output capacitors and the device is fully specified from to +125°C. The TPS74401 is offered in a small × 5mm) QFN package, yielding a highly compact total solution size. For applications that require additional power dissipation, the DDPAK (KTW) package is also available.
