Part Number: TPS746 Are there any known problems with the LDO LT3032IDE when using long leads in conjunction with ferrite beads and common mode chokes at the input? I am a bit concerned about the stability of the LDO.
Hi Xiaoxiang,
My mistake, it's not an integral. Upon further review it looks like the author is using the "S" symbol to denote the "sensitivity analysis". Thus in this example, "the sensitivity of Vout with respect to R1 is equal to - R2 / (R1 + R2…
Part Number: TPS746-Q1 Hi,
From the datasheet,we see the relationship between IOUT and foldback current limit. First, IOUT reaches current limit which is 1.5A. Then Vout decreases to 0.4*3.3V, IOUT is limited to short current which is 680mA typically…
Part Number: TPS746 Hello,
I am using TPS74601 to generate 3.3V o/p with i/p from 3.7V to 5V. I am not able to get expected o/p. Even I change values of F/B resistors R18 to 33K & R20 to 6.6K, Still o/p is not 3.3V constant. F/B pin voltage is stable…
Part Number: TPS746-Q1 The datasheet notes that the device into-to-output resistance is the Rdson of the PMOS device when operating in the linear region. What is that resistance? I would like to calculate the power losses while operating in this mode…
Part Number: TPS746-Q1 Hello I am looking to find the Weight for this part number: TPS74618PQWDRBRQ1 , VOLTAGE REGULATOR, 1.8V. I have looked in the Specification Data sheet and i could not find it. Can I please be assisted with obtaining the Weight for…
Part Number: TPS746-Q1 Hello I am looking to find the Weight for this part number: TPS74610PQWDRBRQ1 , VOLTAGE REGULATOR, 1.0V. I have looked in the Specification Data sheet and i could not find it. Can I please be assisted with obtaining the Weight for…
Part Number: TPS746-Q1 Could you please provide the Shutdown from Enable timing diagram of TPS74601?
The picture below shows the power-on and power-off test chart of the TPS74601 power supply. The power-off time is much longer than the power-on time…
Part Number: TPS746-Q1 Hi expert,
My customer asked a question about LDO overshoot and undershoot.
Can you help explain how overshoot and undershoot are calculated? The customer is using TPS74601-Q1.
Thanks

Hi team,
The customer found that there was a Cff feedforward capacitor in the recommended design of TPS74601. The customer installed a 10nF capacitor, but this affected the power supply rise time. Want to confirm that this capacitor…
