LM1084: Transient Thermal Resistance

Kuramochi Tadahiko

Part Number: LM1084

Hi,

Could you tell me the transient thermal resistance of LM1084?

My customer's usage is follows(with heatsink);

VIN=12V, Vout=7V, Iout=1.6A(during 5sec)

Best Regards,

Kuramochi

    Hi Kuramochi,

    Since your pulse duration is 5 seconds, your transient thermal resistance after 5 seconds is pretty much similar to the one on the datasheet under thermal information section. Unfortunately we don't have the data for the transient thermal resistance from 0 seconds to 5 seconds.
