Product Summary
The TPS70451PWPR is a dual-output low-dropout voltage regulator with integrated svs for split voltage systems. The TPS70451PWPR is capable of supplying 1 A and 2 A by regulator 1 and regulator 2 respectively. Quiescent current is typically 185 uA at full load. Differentiated features, such as accuracy, fast transient response, SVS supervisory circuit (power on reset), manual reset input, and independent enable functions provide a complete system solution. The TPS70451PWPR has fixed 3.3-V/2.5-V, 3.3-V/1.8-V, 3.3-V/1.5-V, 3.3-V/1.2-V, and adjustable voltage options.
