Part Number: TPS7A88 Other Parts Discussed in Thread: TPS7A85 , TPS74401 Hi team,
Customer is going to design TPS7A8801 for 5.5Vin and 3.3Vout with 0.6Aload. For a simple calculation :
(5.5-3.3)*0.6 = 1.32W
Tj = 85 + RθJA * 1.32 = 85 + 33*1.32…
Hi Franco,
We do not have an application note specifically for the TPS7A33, but we do have the following reference design for the TPS7A85 (low voltage positive 4A LDO).
I hope this helps.
Hi Jeff,
We have the following reference design which can be used to force sharing between LDO's. This takes advantage of the fact that the TPS7A85 has an NR/SS pin which is the internal reference. Tying these together forces them to share the same…
Hi Ryan-san,
I just got an additional question from our customer, so could you please tell me that reason why there isn't mentioned in the data sheet that TPS7A47 doesn't provide the reverse current protection feature ? TPS7A85 also doesn't provide…
Part Number: TPS7A85A Hi
I have a question regarding the allowed voltage level for the Ven in the LDO.
From the data sheet: http://www.ti.com/lit/ds/symlink/tps7a85.pdf?&ts=1589468396224
Table 6.3 Recommended operating condition state the level…
Hi Stephen,
Since our last chat, I ordered the TPS7A85 eval board and did some measurements with my eval board. The test setup looks like the image shown below. The wire between the LDO board and my eval board is 4 inches long. I tried to keep it as…
Part Number: TPS7A8300 Other Parts Discussed in Thread: TPS7A7200 , TPS7A89 , TPS7A85 , TPS7A85A , TPS7A54 , UC285 , UC385 Hi team,
Due to the constrained supply of TPS7A8300, we recommended TPS7A8400. However, its supply is still tight. From this thread…
Hello Eric-san,
Thank you for your suggestion. I will suggest the manner which TPS7A85 can use -> Load sprit -> TIDU421.
Best regards,

Part Number: TPS7A47 Other Parts Discussed in Thread: , TPS7A85 Hello all -
I require a high current and low noise (High PSRR + low output noise) 7.5V supply that is capable up to about 2A. We also require good transient response ~100mV pk-pk change…
HI John,
Maybe I can try to answer your question. The TPS7A7200 does have a nice low drop-out but this is rated at 2A. At 2A, the dropout when V OUT is <= 3.3V is only 180mV. For the same pass element, if the current limit allowed 4A, the drop-out…
