ISL78301
40V, Low Quiescent Current, 150mA Linear Regulator for Automotive Applications
FN6705 Rev 2.00 April 7, 2015
The ISL78301 is a high voltage, low quiescent current linear regulator ideally suited for “always-on” and “keep alive” automotive applications. The ISL78301 operates from an input voltage of +6V to +40V under normal operating conditions and operates down to +3V under a cold crank. It consumes only 18µA of quiescent current at no load on the adjustable version.
The ISL78301 is available in a fixed 3.3V, 5V and adjustable output voltage (2.5V to 12V) options. It features an EN pin that can be used to put the device into a low-quiescent current shutdown mode where it draws only 2µA of supply current.
