Hi Oba,
It is difficult to say which approach will work as all validation testing is done using a stable source with low output impedance. Using a resistor divider is definitely not a good approach as DVDD is the main core for the digital. The current…
Thank you for that thorough answer.
3. Parts with active discharge have this warning about possible reverse current damage in the datasheet, commenting that this risk of damage exists despite the active discharge feature. However, is it still correct…
Part Number: TPS798-Q1 Other Parts Discussed in Thread: TPS797-Q1 , Hi Team,
My customer has a qustion.
Q1.
Datasheet P10 7.3.1 Adjustable Operation section has the following description. "The adjustable device is tested and specified with the FB pin tied…
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…
Hi Bernhard,
I do not have this data on hand for TPS797. I would expect your assumption to hold true that it will increase when in dropout, but do not know at this time how much it would increase. I can bench this for you and reply next week if you would…
Hi,
I don't know of any problems associated with the TPS797 and GSM. The TPS797 has a fairly low bandwidth which would make its response to a quickly changing dynamic load difficult. Is your load pulling down the output voltage? Low Iq LDOs are generally…
