The Texas Instruments TPS74401 is a versatile low-dropout (LDO) linear regulator providing a robust power management solution. It features a user-programmable soft-start function to minimize inrush current during startup, making it suitable for applications with specific sequencing requirements.
This LDO supports an input voltage range of 1.1 V to 5.5 V and offers an adjustable output voltage from 0.8 V to 3.6 V. It boasts 1% accuracy over line, load, and temperature variations. The ultra-low dropout voltage is typically 120 mV at 3.0 A, ensuring efficient operation.
The TPS74401 is stable with any output capacitor greater than or equal to 2.2 µF (for the new chip version). It includes an enable input and an open-drain power-good output for easy system sequencing. Available packages include VQFN (RGW, RGR) and DDPAK, providing flexibility for various board space constraints.
Key applications include FPGA power, DSP core and I/O voltages, and post-regulation. Its design flexibility allows for custom solutions meeting the start-up requirements of processors and ASICs.
The input voltage range is 1.1V to 5.5V, and with an external bias supply it can operate down to 0.9V.
The adjustable output voltage range is 0.8V to 3.6V.
Available packages include TO-263 (7), VQFN (RGR and RGW), and DDPAK.
The operating temperature range is -40°C to 125°C.
The typical dropout voltage is 120mV at 3.0A for the new chip and 115mV at 3.0A for the legacy chip.
The accuracy is 1% over line, load, and temperature.
The typical quiescent current is 3mA.
