TPS7A7100RGTR Description

With an input voltage ranging from 1.5 V to 6.5 V, the TPS7A7100RGTR low-dropout (LDO) voltage regulator is designed for applications requiring very low dropout capabilities (140 mV at 1 A). The TPS7A7100 has a unique, user-configurable output voltage range of 0.9 V to 3.5 V, which eliminates external resistors and their associated errors.

The TPS7A7100RGTR provides a quick load-transient response, ceramic output capacitor stability, and better than 2% accuracy over line, load, and temperature. An application can use a soft-start pin to reduce inrush into the load. Sequencing power rails is also possible using an open-drain, power-good signal.
