STM low-dropout linear regulator suits always-on automotive modules

LDO40L 400mA low-dropout linear regulator from ST Microelectronics

The LDO40L 400mA low-dropout linear regulator from ST Microelectronics delivers quiet and efficient power for always-on automotive modules and noise-sensitive loads.

With 45µA quiescent current, the AEC-Q100 qualified part reduces the demand on vehicle batteries to run loads such as body and interior functions that are active when the ignition is off. In addition, the device can be disabled to achieve a shutdown current of 1µA.
