Les A8582 et A8583 utilisent une compensation externe pour s’accommoder à une large gamme de composants de puissance et optimiser la réponse aux transitoires sans sacrifier la stabilité. Ces deux composants régulent des tensions d’entrées allant de 4.7v à 36V pour une tension de sortie pouvant descendre jusqu’à 0.8V. Ils sont aussi capables de fournir un courant d’au moins 2A pour le A8582 et 3.5A pour le A8583. Ils intègrent des protections contre les sous-tensions, contre les surtensions, une protection contre les sur-courants cycle par cycle, un mode de protection contre les courts circuits " hiccup "  et une protection thermique. De plus, le A8583 fournit une protection unique contre les diodes manquantes, contre les circuits ouverts, contre les courts circuits de broches adjacentes, et une protection de toutes les broches contre un court circuit à la masse pour satisfaire les applications les plus exigeantes. Les A8582 et A8583 sont disponibles dans un boitier TSSOP 16 broches avec semelle dissipatrice pour améliorer la dissipation thermique et sont sans plomb avec un étamage des broches 100% étain mat.<\/p>\n
