We are using HT7533 for STM32F105 and ADC power in some of our car stereo head units. We found some reliability issues, especially for the ADC part, which we use to detect resistor values like resistor network for buttons. Please recommend an IC that can take 12V input and output 3.3V, and can work reliably in automotive environment and suitable for ADC power as well.
Hello,
A few more questions to further narrow down the search:
- What kind of current are you expecting at the output?
- Other than an AEC-Q100 rating, are there any other desired features that are needed for your application?
Just as an offhand initial recommendation to your application, I may recommend the following parts:
Let me know what you think of the following and we can home in on getting closer to a solution for you.
Best,
Krishan
