Renesas Electronics Corporation 40V, Low Quiescent Current, 50mA Linear Regulator for Automotive Applications ISL78307FBEBZ-T7A

The ISL78307 is a high voltage, low quiescent current linear regulator ideally suited for “always-on” and “keep alive” automotive applications. The ISL78307 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 ISL78307 is available in 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 1.8µA of supply current. The device features over-temperature shutdown and current limit protection. The ISL78307 is AEC-Q100 qualified. It is rated over the -40°C to +125°C automotive temperature range and is available in an 8 Ld EPSOIC with exposed pad package.
