Description

The TPS70251 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 500 mA and 250 mA by regulator 1 and regulator 2 respectively. Quiescent current of TPS70251 is typically 190 A 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.
