Product Overview: TPS74401RGWRG4

The TPS74401RGWRG4 is a high-precision, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver up to 3A of output current with a dropout voltage of just 250mV at full load. This regulator is optimized for high-performance power supply applications, offering a wide range of output voltages that are adjustable from 0.8V to 3.3V using an external resistor divider.

With its advanced features and robust design, the TPS74401RGWRG4 is suitable for a variety of demanding applications, including FPGA and DSP power supplies, telecommunications, networking equipment, and industrial systems. Its small 20-pin VQFN (RGW) package makes it ideal for space-constrained applications.

Key Features

• High Accuracy: This LDO features a 1% output voltage accuracy over the full temperature range, ensuring reliable performance in critical applications.
• Stable Operation: The TPS74401RGWRG4 is stable with low equivalent series resistance (ESR) ceramic output capacitors, which reduces the size and cost of the power supply design.
• Power Good Output: A built-in power good (PG) output provides a voltage monitoring function, which can be used for power sequencing and fault indication.
• Thermal Protection: Integrated thermal shutdown and overcurrent protection safeguard the device and the system from excessive temperatures and current overloads.
• Adjustable Soft-Start: The soft-start feature limits inrush current and allows for a controlled startup, reducing stress on the input power source.
• Low Noise: With its low-noise performance and fast transient response, this LDO is suitable for noise-sensitive applications such as RF and precision analog circuits.
