NSR33 series 300mA 40-V, Low Iq, Automotive LDO
Datasheet (EN) 0V3
Product Overview
NSR33 series is 300mA low-dropout linear regulator designed for battery-direct-connection automotive applications. Wide supply
voltage range from 3V to 40V makes NSR33 series a good fit for severe operating conditions including load dump, cold cranking and start-stop.
With 5μA quiescent current at light loads, NSR33 series is quite suitable for always-on automotive applications where standby power consumption is strictly restricted.
With integrated compensation implementation, NSR33 series can be stable with low-ESR (1mΩ to 5Ω) ceramic output capacitor, ranging from 1μF to 200μF.
The device features integrated short-circuit-to-GND and thermal shutdown protections. This device operates in ambient temperatures from –40°C to 125°C.
