40V, Low Quiescent Current, 50mA Linear Regulator for
Automotive Applications
ISL78307
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.
