APL5913

APL5913 0.8V Reference Ultra Low Dropout (0.25V@3A) Linear Regulator Features General Description Ultra Low Dropout The APL5913 is a 3A ultra low dropout linear regulator. - 0.25V(typical) at 3A Output Current This product is specifically designed to provide well sup- Low ESR Output Capacitor (Multi-layer Chip ply volatage for front-side-bus termination on Capacitors (MLCC)) Applicable motherboards and NB applications. The IC needs two 0.8V Reference Voltage supply voltages, a control voltage for the circuitry and a High Output Accuracy main supply voltage for power conversion, to reduce - ±1.5% over Line, Load and Temperature power dissipation and provide extremely low dropout. Fast Transient Response Adjustable Output Voltage by External The APL5913 integrates many functions. A Power-On-Re- Resistors set (POR) circuit monitors both supply voltages to pre- Power-On-Reset Monitoring on Both VCNTL and vent wrong operations.
