APL5934 3A, Ultra Low Dropout (0.23V Typical) Linear Regulator Features • General Description The APL5934 is a 3A ultra low dropout linear regulator. The IC needs two supply voltages, one is a control voltage Ultra Low Dropout - 0.23V(typical) at 3A Output Current • (VCNTL) for the control circuitry, the other is a main supply voltage (VIN) for power conversion, to reduce power dissi- Low ESR Output Capacitor (Multi-layer Chip Capacitors (MLCC)) Applicable • • pation and provide extremely low dropout voltage. The APL5934/B integrates many functions. A Power-On- 0.8V Reference Voltage High Output Accuracy Reset (POR) circuit monitors both supply voltages on VCNTL and VIN pins to prevent erroneous operations. - ±1.5% over Line, Load, and Temperature Range • • • Fast Transient Response The functions of thermal shutdown and current-limit protect the device against thermal and current over-loads. A Adjustable Output Voltage POK indicates the output voltage status with a delay time set internally.
