APL5620 2A, Ultra Low Dropout (0.24V Typical) Linear Regulator Features * * * * * * * * * * * * * * General Description Ultra Low Dropout - 0.24V (typical) at 2A Output Current The APL5620 is a 2A ultra low dropout linear regulator. The IC needs two supply voltages, one is a control volt- 0.8V Reference Voltage age (V CNTL) for the control circuitry, the other is a main supply Voltage (VIN) for power conversion, to reduce power High Output Accuracy - 1.5% Over Line, Load, and Temperature Range dissipation and provide extremely low dropout voltage. The APL5620 integrates many functions. A Power-On-Re- Fast Transient Response Adjustable Output Voltage set (POR) circuit monitors both supply voltages on VCNTL and VIN pins to prevent erroneous operations. The func- Power-On-Reset Monitoring on Both VCNTL and VIN Pins tions of thermal shutdown and current-limit protect the device against thermal and current over-loads. A POK Internal Soft-Start indicates that the output voltage status with a delay time set internally. It can control other converter for power Current-Limit and Short Current-Limit Protections sequence. The APL5620 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 APL5620 is available in a TDFN3x3-10 package Low Shutdown Quiescent Current ( < 30A ) which features small size as TDFN3x3-10 and an Exposed Pad to reduce the junction-to-case resistance to Shutdown/Enable Control Function Simple TDFN3x3-10 Package with Exposed Pad extend power range of applications.
