Part Number: TPS797-Q1 Tool/software: Dear engs.
how do you calculate the Mission Profile for the TPS797-Q1 LDO in an automotive application?
Best regards
Part Number: TPS797 Hi All,
We are planning to perform PSRR testing for TPS79733 LDO.
We need block diagram of test setup and list of test equipments with details technical specifications.
Signal generator/Oscilloscope.

Hello Team,
according to https://www.ti.com/lit/pdf/slva079 the accuracy of the LDO could be calculated by this formula:
but the TPS797 data sheet does not provide Vo,a (error amplifier voltage drift) and Vo,ref (reference…
Part Number: TPS797 Hi,
We are considering to use TPS797, or more specifically TPS79733. One of its tasks would then be to act as reference voltage for some ADC measurements. Therefore we would like to ensure that we understand the accuracy details…
Part Number: TPS797-Q1 Other Parts Discussed in Thread: TPS797 Hi every one, I design a PCB and I am going to use the TPS797 LDO. I don't want to use PG pin. My question is:
Can I straight ground the pin and avoid the pull up resistor? Can I have common…
Part Number: TPS797 Hi team,
I have some question about TPS797 datasheet. please help clarify it.
1. in the figure 5, the Vin=2.8V, Vout=3.3V. I think the Vout shout be 1.8V, right?
2. in the figure 11, can the TPS79718 output 3.3V to power MSP430…

I am looking for an LDO with:
very low quiescent current (sub microamp)
1.8V
50mA max
Small footprint
Low cost in volume
Only device I found is…
Part Number: TPS797-Q1 Hi again,
One more question.. According to the datasheet two electrolitic capacitors are required for input (0.1uF) and output (0.47uF).Can I use ceramic capacitors instead of polarized?
Best regards

Part Number: TPS797 Hi team,
I'm using TPS797 in one of my applications. If you have a unused open drain output, is it better from a total current draw perspective to leave it open, or tie it high, or maybe low?
Thanks,
Brian
Matt,
Did you ever find a solution to this? I came across it and was interested in what might be causing this as well. Do you have any external circuitry on the HDQ line when running the tests?
My first thought is is there any way the battery was…
