L99VR02J

L99VR02J is an automotive linear voltage regulator with configurable output voltage having 500mA current capability. The LDO delivers up to 500mA of load current. It consumes as low as 1μA of quiescent current when the regulator is disabled. The input is 40V tolerant to withstand load dump, while the operating input voltage range is between 2.15V and 28V. It features enable, reset, autonomous watchdog, advanced thermal warning, fast output discharge, and Ishort control. The regulator output current is internally limited. The device is protected against short-circuit and overload, besides it features over-temperature protection. The short current value is configurable by external resistance. It can operate both in post-regulation, attached to a pre-regulated voltage or directly connected to the battery.
