TPS74301KTWR Description

Short technical summary and product information.

The Texas Instruments TPS74301KTWR is a versatile linear voltage regulator designed for robust power management applications. It features an adjustable output voltage ranging from 0.8V to 3.6V, with a typical ultra-low dropout of just 55mV at 1.5A. The device supports input voltages as low as 0.9V when an external bias supply is used.

Key electrical characteristics include 1% accuracy over line, load, and temperature variations, and a Power Supply Rejection Ratio (PSRR) of 73dB to 42dB across a frequency range of 1kHz to 800kHz. Protection features include over current, over temperature, short circuit, and under voltage lockout (UVLO).

The TPS74301KTWR is available in a surface-mount DDPAK/TO-263-7 package, suitable for various electronic designs. It operates within an ambient temperature range of -40°C to 125°C. The regulator includes control features such as Enable, Power Good (open-drain), and Tracking, facilitating flexible power-up sequencing for complex systems like FPGAs and DSPs.
