增强型产品单路输出 3A LDO、可调节电压（0.8V 至 3.3V）、快速瞬态响应、可编程软启动

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 • Soft-Start (SS) Pin Provides a Linear Startup with Ramp Time Set by External Capacitor\n• Supports Input Voltages as Low as 0.9 V with External Bias Supply\n• Ultra-Low Dropout: 115 mV at 3.0 A (typ)\n• Excellent Transient Response\n• Active High Enable\n• Controlled Baseline\n• One Fabrication Si;
