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.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
4. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
5. For JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Recommended Operating Conditions, unless otherwise noted. VIN = 14V, IOUT = 1mA, CIN = 0.1μF,
COUT = 10μF, TA = TJ = -40°C to +125°C, unless otherwise noted. Typical specifications are at TA = +25°C. Boldface limits apply across the operating
temperature range, -40°C to +125°C.
