40V, Low Quiescent Current, 50mA Linear Regulator for Automotive Applications  
The ISL78307 is a high voltage, low quiescent current linear  
Features  
regulator ideally suited for “always-on” and “keep alive”  
• Optimized for “always-on” automotive applications  
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.  
• 18µA typical quiescent current  
• Ensured 50mA output current  
• Operates through cold crank down to 3V  
• 40V tolerant logic level (TTL/CMOS) enable input  
• 1.8µA of typical shutdown current  
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.  
• Low dropout voltage of 120mV at 50mA  
• Fixed +3.3V, +5.0V and adjustable output voltage options  
• Stable operation with 10µF output capacitor  
• Thermal shutdown and current limit protection  
• -40°C to +125°C operating temperature range  
• Thermally enhanced 8 Ld exposed pad SOIC package  
AEC-Q100 qualified  
The ISL78307 is AEC-Q100 qualified. It is rated across the  
-40°C to +125°C automotive temperature range and is  
available in an 8 Ld EPSOIC with exposed pad package.  
Applications  
• Automotive  
• 6kV ESD HBM rated  
• Industrial  
• Pb-free (RoHS compliant)  
• Telecom
