Product overview
Description
The L99VR02XP is a low dropout dual linear regulator designed for automotive applications available in a PowerSSO-36 package. The LDO delivers an output current up to 2 x 250 mA, and consumes a quiescent current as low as 1 μA (per each output) 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. 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 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.
