Regulator chip draws ultra-low quiescent current
The MAX16910 is an ultra-low quiescent current, high-voltage linear regulator with a reset output. This 200mA linear regulator consumes only 20microamps (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 from a wide, 3.5V to 30V input-voltage range to withstand cold-crank and double-battery conditions; it can also operate during load-dump conditions up to 45V. Additionally, the integrated open-drain reset output with adjustable delay eliminates the need for an external reset IC. Thus, the MAX16910 is ideal for always-on automotive applications in which small solution size and power efficiency are critical.
The MAX16910 has three pin-selectable output-voltage configurations: fixed output voltages of 3.3V or 5V, or an externally adjustable output-voltage range from 1.5V to 11V. The reset output has a delay that is adjustable through a small external capacitor. Additional protection features include a short-circuit current limit and thermal shutdown.
The MAX16910 is fully specified over the -40 degrees Celsius to +125 degrees Celsius automotive temperature range. It is AEC-Q100 automotive qualified and is available in thermally enhanced 8-pin TDFN and SO packages. Pricing starts at $0.88 (1000-up, FOB USA).
