Frequently Asked Questions
What input voltage range does the TPS79925QDDCRQ1 support for automotive 12V systems?
The TPS79925QDDCRQ1 accepts an input voltage of 2.7V to 6.5V maximum, so it is not directly powered from a 12V automotive rail. It requires a pre-regulator stage stepping down to under 6.5V, then regulates to a fixed 2.5V output with only 100mV dropout voltage minimum.
How does AEC-Q100 qualification affect the TPS79925QDDCRQ1 temperature operating range?
AEC-Q100 Grade qualification certifies the TPS79925QDDCRQ1 to operate reliably across the full automotive temperature range of -40°C to 125°C junction temperature. This includes thermal stress testing, humidity resistance, and electromigration qualification, making it suitable for under-hood and cabin automotive electronics.
Can TPS79925QDDCRQ1 power a 3.3V microcontroller if used with a 3.4V supply?
No, TPS79925QDDCRQ1 is fixed at 2.5V output, not 3.3V. With a 3.4V supply and 100mV dropout, it can barely maintain 2.5V output but the output is 0.8V below 3.3V. For 3.3V output with 3.4V input, a different LDO such as TPS799xx family variant with 3.3V fixed output is required.
