Description

The TPS725xx family of 1-A low-dropout (LDO) linear regulators has fixed voltage options available that are commonly used to power the latest DSPs, FPGAs, and microcontrollers. An adjustable option ranging from 1.22 V to 5.5 V is also available. The integrated supervisory circuitry provides an active low RESET\ signal when the output falls out of regulation. The no capacitor/any capacitor feature allows the customer to tailor output transient performance as needed. Therefore, compared to other regulators capable of providing the same output current, this family of regulators can provide a stand alone power supply solution or a post regulator for a switch mode power supply.

These regulators are ideal for higher current applications.
