NSR31 series 40-V, 150-mA, Low Quiescent Current,
Automotive Low-Dropout Regulator Datasheet (EN) 1.0
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 startstop.
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.
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.
