Part Number: LP2998 Hi,
Here my customer got a marking & X-ray lead-farme matter.
In attached photo the left side parts is from their history and the right side parts is now they get.
They have asking here have two different fort type and PIN 1 on…
Part Number: LP2998-Q1 Other Parts Discussed in Thread: LP2998 Hi!
I wonder if LP2998-Q1 can work as the cell-balancing socket for the super cap. If so, could you please tell me the principle and the realization circuit?I wish to realize the cell balancing…
Part Number: LP2998-Q1
Hello LP2998-Q1 team,
Our customer needs the thermal parameters for the LP2998-Q1. The datasheet only lists the R(Theta-J-A). Can we provide the R(Theta-J-C) and any other values we have available, like Psi-JB, Psi-JT?
I found…
Part Number: LP2998 Hi
I have an additional question.
Regarding VREF accuracy, at JEDEC standard the accuracy is defined +/-2%. However the accuracy of LP2998 is exceed that standard.
LP2998 ; VREF_max = 0.937V@VDDQ=1.8V and VREF_max = 0.986V@VDDQ=1.9V…
