Part Number: TPS731 Hi, There was a problem that TPS73101 did not start up due to customer's evaluation. I attach the waveform at the time of problem occurrence. And customer's circuit is below. TPS73101DBVRG4.pdf
When input voltage ON/OFF repeated…
Part Number: TPS731 Hello,
My customer considers the use of TPS73101.
In the data sheet , ・The maximum rating of the VEN pin is -0.3 V to 6 V. ・EN pin high (enabled) is 1.7 V to VIN.
Does it work if we input a value of VIN ~ 6 V to VEN?
(conditions) VIN…
Other Parts Discussed in Thread: TPS799 , TLV713 , TPS731 Hello there,
I've been trying to spec an equivalent to the TPS73101 but I can't find anything that is cap-free (found the TPS799 and I'm wondering if that's the best option). Would you be able to…
Other Parts Discussed in Thread: TPS731 Hi
I simulated TPS731 using Webench of Japanese version in VIn=2.7 ~ 3.9V, Vout=1.2V, Iout=0.1A, Ta=100℃.
I couldn't simulate to become fixed Vout is 5V.
But in United States version, I cold simulate it.
Is…
Hi
My customer considers the use of TPS73101.
They calculate Vout drop with a rise in temperature when Vin=2.7 ~ 3.9V, Vout=1.2V, Iout =100mA.
But there isn't reference materials in datasheet.
Could you tell me the method of calculation it or give…
Hi Jerry,
If you are operating at 4.5 V input and you need the highest output at 50 mA, then the LP3982 will get you there with just 20-30mV of headroom depending on the temperature. See these graphs in the LP3982 datasheet.

Part Number: TPS736 Other Parts Discussed in Thread: TPS731 Hello guys,
One of my customers was going to use TPS73115 for their new product mass-productions.
But they knew it was difficult to prepare the device by their due date because TPS73115 lead time…
Dear John Cummings,
Thank you for your reply. I understand that TPS793 doesn't meet the requirements.
One of the reasons I considered the TPS793 was price.
I want to talk to a customer on TPS731.
Yours sincerely,
Dear Mr. Hall
OK, I was asking to know what to expect for a voltage drop across the bridge and to check if the ADS1261's IDAC compliance range would be exceeded (i.e. V AINCOM cannot exceed AVDD - 1.1V for the IDAC to work). Since you have a 3.6 kOhm…
