What are the key features of TPS79118DBVRG4Q1?
- Ultra-low dropout voltage of only 38 mV typical enables regulation from near-depleted battery cells and closely spaced input/output voltage rails
- AEC-Q100 automotive-grade qualification (Q1 suffix) ensures reliable operation across extended temperature and stress conditions for vehicle electronics
- 2.7V to 5.5V input range with fixed 1.8V output and 0.0058% max line regulation provides stable power for sensitive digital and analog circuits
- Compact 5-pin SOT-23 package (R-PDSO-G5) with Pb-free, JESD-609 e4 construction minimizes PCB footprint in space-constrained automotive and IoT designs
What is TPS79118DBVRG4Q1 used for?
The TPS79118DBVRG4Q1 is designed for automotive infotainment, ADAS, and body electronics applications requiring a stable 1.8V rail from a Li-ion battery or regulated bus, benefiting from its AEC-Q100 qualification and ultra-low 38 mV dropout. It is also used in industrial IoT nodes, wireless sensor modules, and portable consumer electronics where minimal input-to-output voltage headroom is critical for maximizing battery run time. The low dropout and excellent line regulation make it ideal for powering low-voltage microcontrollers, RF transceivers, and memory devices in both automotive and commercial designs.
