APE8858A

Advanced Power Electronics Corp. FEATURES Low ESR Output Capacitor (MLCC and POSCAP) Applicable 0.5V Reference Voltage with 2% Accuracy Internal Soft-Start Support VID Application Circuit Integrated Hard Short-circuit protection Fast Transient Response Power OK Output with a Delay Time Adjustable Output Voltage Down to 0.5V Over-Temperature Protection RoHS Compliant & Haloge Free APE8858A DESCRIPTION The APE8858A is an ultra low output voltage linear NFET controller. This product is specifically designed to provide well supply voltage for front-side-bus termination on motherboards and NB applications. The APE8858A integrates many functions. A Power-On-Reset (POR) circuit monitors supply voltages to prevent wrong operations. A POK indicates the output status with time delay which is set internally. It can control other converter for power sequence. The APE8858A can be enabled by other power system. A 0.5V reference voltage with 2% accuracy provide tight regulation of the output voltage, enable control, open drain power good signal, under-voltage protection and soft start. The APE8858A is available in a space saving SOT-26 package.
