APL5330

APL5330 Dual Input 2A Low Dropout Regulator Features www.DataSheet4U.com General Description The APL5330 integrates a power transistor to provide regulated voltage with maximum output current of 2A. It also incorporates current-limit, thermal shutdown and shutdown control functions into a single chip. The current-limit circuit limits the maximum output current in overload or short-circuit conditions. The on-chip thermal shutdown provides protection against any combination of overload that would create excessive junction temperature. The output voltage of the APL5330 tracks the reference voltage on VREF pin. A resistor divider connected to VREF pin is usually used to provide reference voltage to the IC. In addition, an external ceramic capacitor and an open-drain transistor connected to VREF pin provides soft-start and shutdown control. Applying and holding a voltage below 0.35V (typ.) to VREF shuts off the output.
