Description

The TPS726126 1-A low-dropout (LDO) linear regulators has fixed voltage options available that are commonly used to power the latest DSPs, FPGAs,and microcontrollers. The integrated supervisory circuitry provides an active lowRESET signal when the output falls out of regulation. The no capaci-tor/any capacitor feature of TPS726126 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 TPS726126 can provide a stand alone power supply solution or a post regulator for a switch mode power supply.

Standby current is less than 1 A.

Unlike some regulators that have a minimum current requirement, the TPS726126 is stable with no output load current.
