    Description

    The TPS708xx is a low dropout voltage regulator with integrated SVS (RESET, POR, or power on reset) and power good (PG) functions. These devices are capable of supplying 250 mA and 125 mA by regulator 1 and regulator 2 respectively. Quiescent current is typically 190 µA 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 TPS708xx family of voltage regulators offers very low dropout voltage and dual outputs. These devices have extremely low noise output performance without using any added filter bypass capacitors and are designed to have a fast transient response and be stable with 10-µF low ESR capacitors.
