Frequently Asked Questions
What is the dropout voltage of TPS7348QDG4 and why does it matter for battery-powered designs?
TPS7348QDG4 has a nominal dropout voltage of 0.15 V, with a maximum of 0.25 V. In battery-powered designs, a low dropout allows the regulator to maintain a stable 4.85 V output even when the input battery voltage drops close to the output level, extending usable battery runtime compared to standard LDOs with 0.5 V to 1.5 V dropout.
What output current and output voltage does TPS7348QDG4 supply, and how accurate is its regulation?
TPS7348QDG4 delivers a fixed 4.85 V output at up to 0.5 A with ±2% output accuracy. The ±2% tolerance ensures the output stays between approximately 4.75 V and 4.95 V across line and load variations, which is tight enough for powering precision analog circuits and 5 V-tolerant digital logic in industrial and automotive applications.
For an automotive sensor module, does TPS7348QDG4 meet the input range requirements of a 6 V to 9 V regulated supply?
Yes, TPS7348QDG4 accepts input voltages from 5.2 V to 10 V (absolute max 11 V), covering a 6 V to 9 V input bus with margin on both ends. Its 8-pin SOIC package and 0.464 W power dissipation rating suit compact automotive sensor PCBs, and its lead-free JESD-609 e4 construction meets modern automotive RoHS requirements.
