Frequently Asked Questions
What input voltage range and dropout voltage does the L4989D013TR support in automotive applications?
The L4989D013TR accepts input voltages from 5.6 V to 31 V in normal operation, with an absolute maximum of 40 V to handle automotive load dump transients. Its typical dropout voltage is just 0.18 V, which means it can regulate correctly with an input only 0.18 V above the output, minimizing power dissipation in 12 V and 24 V automotive supply systems.
How precise is the L4989D013TR output regulation, and why does it matter for automotive ECUs?
The L4989D013TR achieves line regulation and load regulation each at a maximum of 0.025%, providing extremely stable output voltage despite fluctuations in the 12 V automotive battery rail or changes in load current. This level of precision is critical for microcontrollers, CAN transceivers, and sensor signal chains inside automotive ECUs that require supply voltages stable to within a few millivolts over operating temperature ranges from -40°C to +125°C.
What package does the L4989D013TR use, and how does it fit on a standard automotive PCB?
The L4989D013TR is housed in an 8-pin SOIC package (JESD-30 code R-PDSO-G8) with a standard 1.27 mm lead pitch, supplied on tape and reel for automated SMT assembly. This package is widely supported by automotive PCB assembly processes and fits standard 8-pin SOIC footprints, making it straightforward to integrate into ECU boards alongside microcontrollers rated for the -40°C to +125°C automotive temperature range.
