LDO29300P2MTR

[saran]

We have implemented the following circuit. This matches the application circuit given in datasheet of LDO29300P2MTR.But it does not yield expected output. We need help!!

The chip gives expected output 12V but within a fraction of second , voltage drops to 0V.

Thanks for the help. LD29300P2MTR will work on 2.5 V to 14V only. it will never work greater than 14V. We can use the MIC29302WU 

Thanks &Regards,

Sorry, I had also overlooked this during a cursory glance at the data sheet: although the LD29300 can withstand an input voltage of up to 30V, it actually only works up to 14V. This can be found in the data sheet as footnote 1 under table 2:

Above 14 V the device is automatically in shutdown.

So it does!

@saran - always important to understand that these "Absolute Maximum" ratings are not operating specs!
