DESCRIPTION
The APE8858A is an ultra low output voltage linear N-
FET 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.
