L99VR02J General Description

The 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, and consumes as low as 1 μA of quiescent current when the regulator is disabled. The input is 40V tolerant for load dump, while the operating input voltage allowed is in the range between 2.15 V and 28 V. The L99VR02J can be configured, through SELx pins, to generate a fixed 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 integrates features such as enable, reset, autonomous watchdog, advanced thermal warning, fast output discharge and IShort control. The regulator output current is internally limited so that 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 pre-regulated voltage, or directly connected to battery.
