APL5913 Datasheet | Anpec Electronics

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. A thermal shutdown and current VIN Pins limit functions protect the device against thermal and cur- - Internal Soft-Start rent over-loads. A POK indicates the output status with - Current-Limit Protection time delay which is set internally. It can control other con- - Under-Voltage Protection verter for power sequence. The APL5913 is enabled by - Thermal Shutdown with Hysteresis other power system. Pulling and holding the EN pin be- - Power-OK Output with a Delay Time low 0.3V shuts off the output. - Shutdown for Standby or Suspend Mode The APL5913 is available in SOP-8P package which fea- - Simple SOP-8P Package with Exposed Pad tures small size as SOP-8 and an Exposed Pad to reduce - Lead Free and Green Devices Available the junction-to-case resistance, being applicable in (Ro HS pliant) 2~2.4W applications.
