Frequently Asked Questions
What is the output voltage of TPS79425DCQ?
The TPS79425DCQ provides a fixed 2.5V output voltage with ±2% accuracy across the full operating temperature range of -40°C to 125°C. The output is internally trimmed during manufacturing, eliminating the need for external feedback resistors.
What package does TPS79425DCQ use and what are the pin functions?
TPS79425DCQ comes in a 5-pin SOT-23-5 package. The pins are: IN (input voltage), OUT (regulated output), GND (ground), EN (active-high enable), and NC (no connect). The compact package is ideal for space-constrained designs.
Is TPS79425DCQ suitable for automotive applications?
Yes, TPS79425DCQ is AEC-Q100 qualified for automotive use. It operates from -40°C to 125°C, meets automotive reliability standards, and is used in ECUs, infotainment systems, and ADAS sensor power rails.
What are good alternatives to TPS79425DCQ?
Compatible alternatives include the TPS79633DCQ (3.3V version in same SOT-23-5 package), MIC5219-2.5YM5 from Microchip, and XC6206P252MR from Torex. All offer similar 150-300mA LDO performance in compact packages.
What is the minimum input voltage for TPS79425DCQ?
The TPS79425DCQ requires a minimum input voltage of 2.8V (2.5V output + 300mV dropout). The maximum input voltage is 6.5V. For 2.5V output, the regulator maintains regulation down to 2.8V input at 150mA load.
