APL5338A

APL5338A 2A Bus Termination Regulator Features General Description Sourcing and Sinking Current up to 2A The APL5338A linear regulator is designed to provide a VCNTL Supply Voltage Range: 3.1V to 5.5V regulated voltage with bi-directional output current for VIN Supply Voltage Range: 1.2V to 3.6V DDR-SDRAM termination. The APL5338A integrates two power transistors to source or sink current up to 2A. It VTT and VTTREF Voltage Tracks at Half the VREF also incorporates current-limit and thermal shutdown into Voltage a single chip. VTT and VTTREF Voltage with ±10mV Accuracy The output voltage of APL5338A tracks the voltage at VREF Excellent Load Transient Response pin. An internal resistor divider is used to provide a half Stable with 10µF Ceramic Output Capacitor Current-Limit Protection Thermal Shutdown Protection Power-On-Reset Function on VCNTL voltage of VREF for VTTREF and VTT Voltage. The VTT output voltage is only requiring 10µF of ceramic output capacitance for stability and fast transient response. The S3 and S5 pins provide the sleep state for VTT (S3 state) and suspend state (S4/S5 state) for device when S5 and S3, S5 Input Signals for ACPI States S3 are both pulled low the device provides the soft-off for Small MSOP-10P and TDFN3x3-10 Packages Lead Free and Green Devices Available (RoHS Compliant) VTT and VTTREF. The MSOP-10P and TDFN3x3-10 package with a copper pad is available which provides excellent thermal impedance....
