L99VR02J

Overview

The L99VR02J is an automotive-grade low dropout linear voltage regulator in a PowerSSO-12 package. It delivers up to 500 mA of load current with a quiescent current as low as 1 µA when disabled. The device supports an operating input voltage range from 2.15 V to 28 V and withstands 40 V load dump transients. Output voltage is configurable via SELx pins to fixed levels: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 2.8 V, 3.3 V, or 5 V, maintaining ±2% accuracy over temperature. It features enable control, reset output, autonomous watchdog, advanced thermal warning, fast output discharge, and programmable short-circuit current limiting.

Feature Summary

Configurable output voltage selection through digital SELx pins for eight fixed levels
Integrated diagnostic functions including reset output, autonomous watchdog, and advanced thermal warning
Fast output discharge circuit activated upon disable to rapidly remove stored charge
Programmable short-circuit output current controlled by external resistance

Applications

Microcontroller power supplies in automotive body modules
Powering sensors and infotainment processors
Automotive display driver circuits
Post-regulation stages attached to pre-regulated voltages

Procurement Notes

Verify the specific ordering suffix (e.g., TR for tape and reel) against the required packaging format. Confirm that the application environment remains within the specified junction temperature range of -40 °C to 175 °C. Ensure input capacitance meets the minimum requirements for stability under all load conditions.

Selection Notes

Select this component for applications requiring high input voltage tolerance and configurable output levels. Verify that the maximum load current does not exceed 500 mA. Consider the thermal resistance characteristics if operating near the upper temperature limits. Ensure the selected output voltage configuration aligns with the SELx pin logic states at startup.

Part Context

This device belongs to the L99VR02 series of automotive linear regulators designed for robust performance in demanding environments. It utilizes BCD9 technology to achieve low dropout voltage and high precision. The series is AEC-Q100 qualified, ensuring reliability for automotive electronic systems requiring stable power delivery under varying line and load conditions.
