RJR8x0xx · 150/300/450 mA, 60 V Ultra-low Quiescent Current Automotive LDO
3V~60V wide input with up to 45V transient tolerance; fixed 1.8/2.5/3.3/5 V and adjustable 1.8V~15V outputs covering the current range of 12V / 48V systems.
The RJR8x0xx family raises the input voltage rating of the 40V products to 60V (45V transient maximum) and offers three output current levels: 150mA(RJR81xxx), 300mA(RJR83xxx) and 450mA(RJR85xxx). Outputs are available in fixed 1.8V/2.5V/3.3V/5V and adjustable 1.8V~15V versions.
Typical light-load quiescent current is 5µA with shutdown current down to 400nA and 450mV typical dropout at 300mA, meeting the supply requirements of MCUs, CAN transceivers and sensors in 12V/48V automotive systems.
