The input is 40 V tolerant to withstand load dump, while the operating input voltage range is between 2.15 V and

28 V. Each of the L99VR02XP outputs 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 L99VR02XP features enable, reset, autonomous watchdog, advanced thermal warning, thermal cluster, fast

output discharge. Automatic voltage (de)tracking of LDO2 respect the internal LDO1 or of an external voltage

regulator and IShort control. The regulator output current is internally limited so 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 L99VR02XP can operate both in post regulation, attached to a pre-regulated

voltage, or directly connected to the battery.
