RJR710xx · 150 mA, 40V Ultra-low Quiescent Current Automotive LDO
3V-40V wide input with fixed 3.3V/5V output, 5.5µA typical quiescent current and 800nA shutdown current - ideal for always-on systems connected directly to the battery.
The RJR710xx family comprises 150mA automotive-grade LDOs for always-on systems connected directly to the battery. The 3V–40V wide input range tolerates transients up to 42V, with fixed 3.3V(RJR71033) or 5V(RJR71050) output.
Typical light-load quiescent current is only 5.5µA and shutdown current is as low as 800nA; combined with a 300mV typical dropout at 150mA, this noticeably reduces the power consumption of always-on systems. The device operates stably with low-ESR (1mΩ–5Ω) ceramic output capacitors from 1µF to 200µF.
