Description

The TC1304 combines a 500mA synchronous buck regulator and a 300mA low-dropout (LDO) regulator with a power-good monitor to provide a highly integrated solution for applications that require multiple supply voltages. The power-good function monitors the outputs of the Buck and LDO regulators and can provide sequenced startup and shutdown.
