L99VR02J Automotive Linear Voltage Regulator with Configurable Output Voltage having 500mA current capability

L99VR02J is a low dropout linear voltage regulator designed for automotive applications available in PowerSSO-12 packages. The LDO delivers up to 500 mA of load current. It consumes as low as 1 μA of quiescent current when the regulator is disabled. The input is 40 V tolerant to withstand load dump, while the operating input voltage range is between 2.15 V and 28 V.

The L99VR02J can be configured, through SELx pins, to generate a fixed selectable output voltage (0.8 V; 1.2 V; 1.5 V; 1.8 V; 2.5 V; 2.8 V; 3.3 V or 5 V). High output voltage accuracy (±2%) is kept over wide temperature range, line, and load variation.

The L99VR02J 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 an external resistance.

The L99VR02J can operate both in post regulation, attached to a preregulated voltage or directly connected to the battery.
