L99VR033QTR [STMicroelectronics]

L99VR03 is a low dropout linear voltage regulator designed for automotive applications available in VFDFN8L wettable flanks and PWSSO12 package. The LDO delivers up to 300 mA of load current and consumes as low as 800 nA of quiescent current when the regulator is disabled and only 3.5 µA quiescent current at no load. The device is quite suitable for standby microprocessor control-unit systems, especially in automotive applications. The input voltage operating range is up to 40 V. The L99VR03 features enable. The L99VR03 is available in different output voltage options (3.3 V or 5 V). High output voltage accuracy (±2%) is kept over wide temperature range, line and load variation. The regulator output current is internally limited so that the device is protected against short-circuit, as it features over temperature protection.
