The A81805 is a powerful synchronous buck regulator that offers high efficiency over the full load of up to 2.5A. This regulator's unique architecture reduces the amount of EMI generated by the switching components to minimize the number of external components. The A81805 has a very low 6uA quiescent current which will help maximize battery life in standby mode. The input voltage range is wide enough to survive many transients in automotive and industrial applications and not turn off when the voltage drops.
