Dear all,

Would you mind if ask for over-temperature protection of LP2985?

Out customer would like to know about this.

Please answer questions below,

1.If "over-temperature protection" in LP2985 works, is this device shutdown?

2.Could you tell me Threshold value and the deviation of junction temperature to work "over-temperature protection" in LP2985?

It would be great if you could let me know your thoughts on the following the question.

Best regards,

Hi Yu,

Please allow us some time in order to look into this as LP2985 is an older device.

Very Respectfully,

Hi Yu,

I apologize for the delay. Yes LP2985 has thermal shutdown that will typically occur at 150 C junction. It is important to keep in mind that thermal protection is intended for fault protection only and should not be relied on in normal operation. Please ensure that you design your application to remain within the recommended operating temperature range.

Very Respectfully,
Ryan
