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