Part Number: TPS7A91 Hi team,
My customer trying to use TPS7A91 noticed that the their Cin=1uF is too small. But, as it is close to the production, it's difficult to change the Cin to 10uF. So, could you please help me to analyze how 1uF Cin affects…
Part Number: TPS7A91 Hi Team,
My customer finds that when the PG is pull up to Vout. There is a glitch at the PG. And the peak value is different as different pull up resistor. Below is the schematic and waveform (@100k pull up). Could you pls help analyze…
Part Number: TPS7A91 Hi Team,
Could you help to check the accuracy of the Vref over operating temperature range? From the accuracy spec of Vout, it seems with in -1% ~ 1%. I would like to know is Vref accuracy related to Vin and Iout?
Regards, Hail…

Part Number: TPS7A91 Hi Team,
Please help us to get the Case Temperature (Tc) of the Part TPS7A9101 as it is needed for the thermal simulation of our project.
Part Number: TPS7A91 Please let me check about TPS7A91. Table 2 of the data sheet P.18, the combination of output setting to Vout: 3.30V is R1: 3.57kΩ and R2: 1.15kΩ. The combination of R1: 4.7kΩ and R2: 1.5kΩ has a Vout closer to 3.30V.…
Part Number: TPS7A91 Hi team,
Customer is using TPS7A91 in their system generate 1.8V, they use 0.1uF SS cap, and find the output voltage get a small overshoot to 1.8V, then drop ~40mV down to 1.76V, later slow back to 1.8V; below is their test waveform…
