Part Number: TPS7A90 I understand from Figure 36, and the text in the DS how the soft-start system works.
I understand how to use Equation (5) to calculate the "tss" value (soft-start time)
Q1] The equation suggests with C_NSSS = 0nF, that soft…
Part Number: TPS7A90 On the datasheet, page 1 and 2 specify Vout max as 5.7V. On page 1 it specifically states "The TPS7A90 output is adjustable with external resistors from 0.8 V to 5.7 V."
However, on section 8.1.1 (page 17), it states "the…
Part Number: TPS7A90 Other Parts Discussed in Thread: TPS7A91 Hi team,
My customer is using the TPS7A9001 and have 2 different options for SS_CTRL and NR/SS, and they are wondering if one way is better than the other. They both end up having approximately…
Part Number: TPS7A90 Hi
I can see the recommended capacity for Cin and Cout in the datasheet(SBVS324) Page.4.
Is this capacitance considering DC bias characteristic?
Thank you.
Another doubt is regarding Longevity and Suitability of TPS7A90 LDO for New Designs
I am currently using the TPS7A90 LDO in one of my designs and would like to know if it is advisable to continue using this component for new designs. I noticed on the…
Part Number: TPS7A90 Dear Teams,
I am helping my customer test the LDO TPS7A9001 with following schematic diagram. What I found the output voltage is only 0.85V and Vfb is only 0.2V. Do you think the chip is already broken? Or do you have any other suggestions…
Part Number: TPS7A90 Hello team,
My customer uses TPS7A90 for 3.3Vin / 1.8Vout.
My customer sees the output voltage drops after the start-up, and then gradually goes up to the target voltage very slowly in 200ms.
Please find the internal link here for…
Part Number: TPS788 Other Parts Discussed in Thread: TPS7A90 Tool/software: Hi team,
Could you help recommend following parts to meet customer requirement?
-With Soft start control pin, could limit slew rate to 0.5V/ms
-Output current 500mA
-Input 5V …
Part Number: TPS7A90 Other Parts Discussed in Thread: TPS7A91 , Hello,
In my current design, We'd like to connect a pullup resistor from Power Good to VIN (A Maximum of 3.5V) rather than VOUT. I'd really appreciate some confirmation If connecting PG to…
Part Number: TPS7A90 Hi Team,
I have one quick question.
Does TPS7A90 need external diode between Input and output for discharging, if Vout > Vin condition exists in customer use case?
Regards,
