Part Number: TPS730
Hi,
we use TPS73001 for 5V to 2.5V/100mA convertion, C_NR=10nF, feedback resistor R_top=33K, R_bottom=32K, Cff=18pF. As SCH picture below.
TPS73001 claims fast start up time about 50us, and I guess the actual ramping time is enven…
Part Number: TPS730 Other Parts Discussed in Thread: MSP430F2416 , , ADS1292 Hi all,
How can I calculate the power consumed by a low dropout regulator for its own working? In my circuit I have two TPS73033DBVT regulators for powering MSP430 and a class2…
Part Number: TPS730 Other Parts Discussed in Thread: TPS799 , All the device specs are given -40C to +125C. Then the "package option addendum" is -40C to +85C.
This is different from the TPS799 which consistently lists 125C in both locations…
Part Number: TPS730 Hi
I got 2 questions about TPS73018 and TPS73025 from my customer.
1.
The start-up time is written 0.05us(the bypass capacitor is 0.001uF) in datasheet.
My customer use these devices that the bypass capacitor is 0.1uF.
Could you…
Part Number: TPS730 Hi there,
We are using two TPS73001 to generate Vout1=5V and Vout2=2.5V from 5.5V Vin, less than 50mA load for each Vout. Some questions to consult.
1. In datasheet section 8.1.1, the recommended feedback resistor R2 is 30.1K to set…
Hi John,
Thanks for your suggestion and other information. TPS7A39 is also good but is problematic for me because of the package(WSON(10). Pins are difficult to solder by hand.
Would TPS730 also be a good choice in combination with TPS723?
If I now wire…
Stephen, Thanks for the explanation. In addition to your answer, I found material from Texas Instruments. www.ti.com/.../slva079.pdf As a result: Vin = Vout + Vdo (max) is a normal mode of functioning in my case (Vout =3.3, Vdropout = 0.250(max) Vin > 3…
Hi Hari,
Thank you for providing me the information!
Some other low noise choices would be TPS793 and TPS730 which are also P2P with LP5907.
Best Regards,
Wilson
