Overview
Description
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. The device features over-temperature shutdown and current limit protection. The ISL78301 is AEC-Q100 qualified. It is rated over the -40°C to +125°C automotive temperature range and is available in a 14 Ld HTSSOP with an exposed pad package.
