Thermal shutdown for Regulator IC (TPS79718DCKT)

Other Parts Discussed in Thread: TPS797

In our project we are using TI Voltage regulator IC.

We need to know, in this TI Regulator IC (TPS79718DCKT) thermal shutdown is implemented or not?

I didn’t find any thing in latest datasheet.

 

In one of the scenarios, we need to short the Output Voltage to GND?

What is the impact if Regulator output shorted Ground directly?

 

IC specification:-

RG5

IC, SMT, Regulator, LDO, 1.8V, 50mA, SC70

    Hi Sumit,

    TPS797 does not have a traditional specified thermal shutdown.

    I did bench a device today and heat up the device. The output voltage decreased to 0V as the LDO heated up. Upon removing the heat it did startup again. This differs from a traditional thermal shutdown as the device did not cycle itself between shutdown and on (effectively producing a square wave). Furthermore, the shutdown temperature is not specified. Please be sure to keep the maximum operating temperature in mind while you design your application.

    Very Respectfully,
    Ryan
