DESCRIPTION
The TPS704xx family of devices consists of dual-output, low-dropout
voltage regulators with integrated SVS (RESET, POR, or power on reset) and power good (PG) functions. These devices are capable of supplying 1 A and 2 A by regulator 1 and regulator 2 respectively. Quiescent current is typically 185 mA at full load. Differentiated features, such as accuracy, fast transient response, SVS supervisory circuit (power on reset), manual reset input, an...
