RJR81xxx / RJR83xxx / RJR85xxx · 150 / 300 / 450 mA, 60 V Ultra-low Quiescent Current Automotive LDO

3 V–60 V wide input with up to 45 V transient tolerance; fixed 1.8/2.5/3.3/5 V and adjustable 1.8 V–15 V outputs covering the current range of 12 V / 48 V systems.

The RJR8x0xx family raises the input voltage rating of the 40 V products to 60 V (45 V transient maximum) and offers three output current levels: 150 mA (RJR81xxx), 300 mA (RJR83xxx) and 450 mA (RJR85xxx). Outputs are available in fixed 1.8 V / 2.5 V / 3.3 V / 5 V and adjustable 1.8 V–15 V versions.

Typical light-load quiescent current is 5 µA with shutdown current down to 400 nA and 450 mV typical dropout at 300 mA, meeting the supply requirements of MCUs, CAN transceivers and sensors in 12 V / 48 V automotive systems.
