Hi.

Ask questions during the design of the LM35AH NDV package.

--> Is the bottom correct?

--> Is the TOP correct?

--> Is this the drawing from the bottom of the PCB?

Is the pin map shown below correct?

1. +VS

2. GND

3. Vout

please answer me.

Thanks.

Hi Chun,

Thank you for reaching out to us. I'm sorry for the long delayed response. In section 5 pin configuration and functions, the illustration diagram for the NDV package is wrong as well as the label "bottom view". The dashed line circle of the +Vs and Vout is represented looking from top view, and since the GND pin is connected to the package, there is no isolation. Therefore, the illustration diagram should be labelled top view.

The ePOD diagram of page 27 that you asked about is bottom view since the pin outlines are solid. To check this, if you place the mirror 90° angle perpendicular to the image, you should see the reflection of the image to top view by looking into the mirror.

The ePOD diagram of page 28 is top view if you are using the same mirror analogy for the ePOD diagram of page 27, the pinout should reflect to similar to page 28. The notch is facing to northwest.

Here is the pinout: pin 1 (+Vs), pin 2 (Vout), pin 3 (GND).

Hope this helps. Let me know if you have further question.

Aaron
