Product Summary

The TPS70445PWPR is a dual-output, low dropout voltage regulator with integrated SVS for split voltage system. The TPS70445PWPR consists of dual-output, low-dropout voltage regulators with integrated SVS (RESET, POR, or power on reset) and power good (PG) functions. The TPS70445PWPR is capable of supplying 1 A and 2 A by regulator 1 and regulator 2 respectively. Quiescent current is typically 185 mA at full load.
