ISL78307 FN7658
Rev 3.00
April 7, 2015 40V, Low Quiescent Current, 50mA Linear Regulator for Automotive Applications
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 18ВµA of quiescent current at no load on the
adjustable version. Features 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 1.8ВµA of supply current.
The device features over-temperature shutdown and current
limit protection. 40V tolerant logic level (TTL/CMOS) enable input The ISL78307 is AEC-Q100 qualified. It is rated over the -40В°C
to +125В°C automotive temperature range and is available in
an 8 Ld EPSOIC with exposed pad package.
