The TPS7A7300 low-dropout (LDO) voltage regulator is designed for applications requiring very-low dropout capability ( 240 mV at 3 A) with an input voltage from 1.5 V to 6.5 V. The TPS7A7300 offers an innovative, user-configurable, output-voltage setting from 0.9 V to 3.5 V, thus eliminating external resistors and any associated errors.

The TPS7A7300 has very fast load-transient response, is stable with ceramic output capacitors, and supports a better than 2% accuracy over line, load, and temperature. A soft-start pin allows for an application to reduce inrush into the load. Additionally, an open-drain, power-good signal allows for sequencing power rails.

The TPS7A7300 is available in a 5-mm × 5-mm, 20-pin VQFN package.
