The ultralow quiescent current MAX16910 from Maxim Integrated Products is a high-voltage linear regulator with a reset output. This 200-mA linear regulator consumes only 20 microamps (typ) of quiescent current to conserve battery life in always-on automotive applications. Designed for automotive environments using Maxim’s robust BiCMOS process, the MAX16910 is capable of operating a 3.5 to 30 V input-voltage range to withstand cold-crank and double-battery conditions. The AEC-Q100 automotive-qualified device can also operate during load-dump conditions up to 45 V. Adjustable through a small external capacitor, the MAX16910’s integrated open-drain reset output with adjustable delay eliminates the need for an external reset integrated circuit. Additional protection features include a short-circuit current limit and thermal shutdown.
