(0.5V) and the very low supply current make it particularly suitable for low noise and low power applications such as PDA, MICRODRIVE and other data storage applications while the used high voltage technology makes this device suitable for consumer applications such as MONITORS AND SET-TOP-BOX. For each VO a Shutdown Logic Control function is available (TTL patible) to decrease the total power consumption.
