TPS74401 - 3.0-A Ultra-LDO

General Description

The TPS74401 low-dropout (LDO) linear regulators provide an easy-to-use robust power-management solution for a wide variety of applications.

The userprogrammable soft-start minimizes stress on the input power source by reducing capacitive inrush current on start-up.

Key Features

  • 1 Input Voltage Range: 1.1 V to 5.5 V.
  • 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 0.9 V With External Bias Supply.
  • Adjustable Output: 0.8 V to 3.6 V.
  • Ultra-Low Dropout: 115 mV at 3.0 A (typical).
  • Stable With Any or No Output Capacitor.
  • Excellent Transient Response.
  • Open-Drain Power-Good (VQFN.
