TLV757P: Please let me know the PDmax (maximum power dissipation) at Ta= -10 °C, Ta= +25 °C , Ta= +60 °C.

Hello E2E team. 

One of our customer want to kown the PDmax (maximum power dissipation) at  Ta= -10 °C, Ta= +25 °C , Ta= +60 °C. 

I would appreciate it if you could let me know these parameter.

Thanks & Best regards. 

Jonathan.

    Hi Jonathan,

    The maximum power dissipation can be estimated with the information provided in our Thermal Information Table.

    We can use the Theta-ja metric to calculate the maximum power dissipation using the following equation:

    The maximum junction temperature to remain within the operating temperature range for TLV757P is 125 C; therefore, plugging in the Theta-ja and Tj(max) we get the following:

    Keep in mind that board layout and proximity to other heat sources will impact the thermal performance of an LDO.  As such, it is still important to prototype and test your application.

    Very Respectfully,

    Ryan
