Advanced Power Electronics Corp. FEATURES Sink and Source up to 2.5Amp Integrated Power MOSFETs High Accuracy Output Voltage at Full-Load Output Adjustment by Two External Resistors Built-in Soft-start Function Current Limiting Protection On-Chip Thermal Protection Available in ESOP-8 (Exposed Pad) Packages VIN and VCNTL Under Voltage Protection RoHS Compliant and 100% Lead (Pb)-Free Halogen Free Product APPLICATION Desktop PCs, Notebooks, and Workstations Graphics Card Memory Termination Set Top Boxes, Digital TVs, Printers Embedded Systems Active Termination Buses TYPICAL APPLICATION APE8977MP 2.5A LINEAR REGULATOR DESCRIPTIOON The APE8977MP is a simple, cost-effective and high-speed linear regulator. The regulator is capable of actively sinking or sourcing up to 2.5A while regulating an output voltage to within 40mV. The desired output voltage can be programmed by two external voltage divider resistors of the REFEN pin. The APE8977MP also incorporates a high-speed differential amplifier to provide ultra-fast response in line/load transient. Other features include extremely low initial offset voltage, excellent load regulation, current limiting in bi-directions and on-chip thermal shut-down protection. Built-in soft-start function avoids a misoperation by inrush current. The APE8977MP are available in the ESOP-8 (Exposed Pad) surface mount packages. .
