Part Number: TPS797
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 voltage drift…
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.
1) Minimum Bandwidth.
2) Minimum…
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 correctly…
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
Nick
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…
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
