APL5920

APL5920 2A, Ultra Low Dropout (0.24V Typical) Linear Regulator Features Ultra Low Dropout - 0.24V (Typical) at 2A Output Current 0.8V Reference Voltage High Output Accuracy - ±1.5% Over Line, Load, and Temperature Range Fast Transient Response Adjustable Output Voltage Power-On-Reset Monitoring on Both VCNTL and VIN Pins Internal Soft-Start Current-Limit and Short Current-Limit Protections Thermal Shutdown with Hysteresis Open-Drain VOUT Voltage Indicator (POK) Low Shutdown Quiescent Current (< 30µA ) Shutdown/Enable Control Function Simple SOP-8P Package with Exposed Pad Lead Free and Green Devices Available (RoHS Compliant) General Description The APL5920 is a 2A ultra low dropout linear regulator. The IC needs two supply voltages, one is a control voltage (V CNTL) for the control circuitry, the other is a main supply Voltage(VIN) for power conversion, to reduce power dissipation and provide extremely low dropout voltage. The APL5920 integrates many functions. A Power-On-Reset (POR) circuit monitors both supply voltages on VCNTL and VIN pins to prevent erroneous operations. The functions of thermal shutdown and current-limit protect the device against thermal and current over-loads. A POK indicates that the output voltage status with a delay time set internally. It can control other converter for power sequence. The APL5920 can be enabled by other power systems. Pulling and holding the EN voltage below 0.4V shuts off the output. The APL5920 is ...
