NSR31 series  
40-V, 150-mA, Low Quiescent Current,  
Automotive Low-Dropout Regulator  
Datasheet (EN) 1.0  
Applications  
Product Overview  
NSR31 series is 150 mA low-dropout linear regulator  
designed for battery-direct-connection automotive  
applications. Wide supply voltage range from 3 V to 40 V  
makes NSR31 series a good fit for severe operating  
conditions including load dump, cold cranking and start-  
stop.

Cluster  
Body Control Module  
Battery Connected Always-On System  
With 5 μA quiescent current at light loads, NSR31 series is  
quite suitable for always-on automotive applications where  
standby power consumption is strictly restricted.  
Device Information  
With integrated compensation implementation, NSR31  
series can be stable with low-ESR (1 mΩ to 3 Ω) ceramic  
output capacitor, ranging from 2.2 μF to 100 μF.
