APL5330
Dual Input 2A Low Dropout Regulator
Features
•
•
Fast Transient Response
High Output Accuracy
- ±20mV over Load, Output Voltage Offset and
Temperature
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.
