Part Number: TPS7A7100
In another question I asked about external resistors I accidentally populated. In that same design I realize I left CFF populated at 100pF.
The data sheet strongly recommends 220pF, the webench design says to not populate CFF…
Part Number: TPS7A7100 I designed a board with the TPS7A7100RGWR. I connected the 1.6V, 800mV, and 400mV pins the ground to get the 3.3V configuration.
Somehow I ended up with external resistor in the design, even though I can't change the pins going…
Part Number: TPS7A7100 Tool/software: I've encountered a problem where when I turn on the TPS7A7100, the Vout is short-circuited to ground. When I use a multimeter with the red probe touching Vout and the black probe touching GND, it resumes normal output…
Part Number: TPS7A7100 Other Parts Discussed in Thread: TPS7A37 Hi,
I have read all the posting in https://e2e.ti.com/ regarding this issue but could not find a proper solution to it.
What we understand is the need for a reverse bias diode connecting…
Part Number: TPS7A7100 Hi team,
I have found that when the power supply stops, a reverse current flows and the device stops working. As a stopgap measure, I added a Schottky barrier diode between output and GND. Should I install one between output and…
Part Number: TPS7A7100 Other Parts Discussed in Thread: TPS7A8300 Custoemr used one tps7a7100 to convert 3.3V to 1.8V, and due to Vmargin IC limitation, the FB divider resistors have to be chosen very low resistance, eg. 1k Rtop and 0.383k Rbot.

I would like to use TI TPS7A7100 LDO, my question is regarding to the input capacitor, in the data sheet page 23 8.2.2.3 Input Capacitor Requirements it is recommended to use a capacitor…
Part Number: TPS7A7100 Hi, Customers use TPS7A7100 under the following conditions: ・Vin=3.3V, Vout=3V, Iout≒300mA ・Cin:0.1uF, Cout=10uF, 1uF, 0.1uF (ceramic cap), Cff=0.1uF In the above situation, Output oscillation occurred which is thought to be caused…
Part Number: TPS7A7100 Hi
I think there are the difference to connection method the SNS terminal written in datasheet. Upper schematic in figure 22~27, the SNS terminal is located outside of the FB terminal, but the FB terminal is located outside…
Hi Ashvin,
The Vout range of 0.9V to 3.5V is our recommended output range. TPS7A7100 is characterized and tested over this output range, as such in order to achieve the Electrical Characteristics table specifications, Vout minimum is 0.9V. With an…
