The TPS74401RGWT is a Single Output Low Dropout Regulator with fast transient response and programmable soft-start for a wide variety of applications. The 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 application-specific integrated circuits (ASICs). The enable input and power-good output allow easy sequencing with external regulators. This complete flexibility lets the user configure a solution that meets the sequencing requirements of field-programmable gate arrays (FPGAs), digital signal processors (DSPs) and other applications with specific start-up requirements. A precision reference and error amplifier deliver 1% accuracy over load, line, temperature and process. The LDO is stable without an output capacitor or with ceramic output capacitors.

• Soft-start (SS) pin provides a linear start-up 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
• Ultra-low dropout (115mV at 3.0A (typical))
• Stable with any or no output capacitor
• Excellent transient response
• Open-drain power-good (VQFN only)
• Green product and no Sb/Br
