APL5934

APL5934 3A, Ultra Low Dropout (0.23V Typical) Linear Regulator Features General Description Ultra Low Dropout The APL5934 is a 3A ultra low dropout linear regulator. - 0.23V(typical) at 3A Output Current The IC needs two supply voltages, one is a control voltage Low ESR Output Capacitor (Multi-layer (V ) for the control circuitry, the other is a main supply CNTL Chip Capacitors (MLCC)) Applicable voltage (VIN) for power conversion, to reduce power dissi- 0.8V Reference Voltage High Output Accuracy pation and provide extremely low dropout voltage. The APL5934/B integrates many functions. A Power-OnReset (POR) circuit monitors both supply voltages on - ±1.5% over Line, Load, and Temperature Range VCNTL and VIN pins to prevent erroneous operations. Fast Transient Response The functions of thermal shutdown and current-limit pro- Adjustable Output Voltage tect the device against thermal and current over-loads. A Power-On-Reset Monitoring on Both VCNTL and POK indicates the output voltage status with a delay time VIN Pins set internally. It can control other converter for power Internal Soft-Start sequence. The APL5934/B can be enabled by other power Current-Limit and Short Current-Limit Protections systems. Pulling and holding the EN/ENB voltage below Thermal Shutdown with Hysteresis Open-Drain VOUT Voltage Indicator (POK) 0.4V shut/enable off the output. The APL5934 is available in a SOP-8P package which features small size as SOP-8...
