Overview
The L99VR01JTR is an automotive-grade low dropout linear voltage regulator manufactured by STMicroelectronics, housed in a PowerSSO-12 surface-mount package. It delivers up to 200 mA of load current with a quiescent current of ≤1 µA when disabled. The device supports an operating input voltage range from 2.15 V to 28 V and withstands transient load dump events up to 40 V. Output voltage is user-selectable via SELx pins among eight fixed options: 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% precision across wide temperature variations.

Procurement Notes
Verify the specific J suffix indicates the PowerSSO-12 package variant with advanced diagnostics. Confirm AEC-Q100 qualification status matches project requirements. Ensure compatibility with the intended PCB layout for the specified package type. Validate that the selected output voltage configuration aligns with the application's SEL pin logic levels.
Selection Notes
Select this component for applications requiring high junction temperature operation up to 175°C. Choose the J variant specifically for programmable short-circuit current and thermal warning features not present in standard versions. Ensure the design accommodates the required external resistors for IShort and TW pin configurations. Verify input voltage stability meets the 2.15 V minimum requirement during all operating conditions.

FAQ
How is the short-circuit output current configured?
The short-circuit output current is programmable using an external resistor connected between the IShort pin and ground.
What diagnostic functions are available on the TW pin?
The TW pin provides advanced thermal warning by pulling low when temperature exceeds the threshold and generates a square wave signal during output overvoltage events.
