Tool/software:
Hello guys,
One of my customers is evaluating TPSM861257 for their new products.
Their VIN/VOUT conditions are the follows.
VIN=3.3V,
VOUT=2.5V,
IO=450mA
In the evaluation, they found VOUT was +1.96V at 0mA load
The parts they use are the follows.
Cin=10uFx3+0.1uF
Cout=10uFx5+0.1uF
RFBT=104.7kohm
RFBB=33kohm
At this moment, they have the following questions.
Could you please give me your reply.
Q1.
Can TPSM861257 be used for VIN=3.3V, VOUT=2.5V condition?
Q2.
Do you have any idea what this cause is?
Your reply would be much appreciated.
Best regards,
Kazuya.
