Good Day. The TPS76901-HT datasheet says that the TPS76901-HT should only be used to a maximum output of 4.5 V and has a absolute maximum input of 13.5 V. The regular low temperature version of the part is rated to a maximum of 5.5 V out and has an absolute max input of 10V. Both parts have an Absolute Maximum Output (and FB Voltage) of 7 V.
A previous discussion ("TPS76901 Output voltage range",
http://e2e.ti.com/support/power_management/linear_regulators/f/321/t/296672.aspx)
stalled 5+ months ago with the comment " I am still working on tying to find out the information that you have requested as to what is the limiting factor that dictates output voltage be limited to 4.5V for the -HT part and 5.5V for the standard commercial part. Will advise as soon as I have a concrete response to it."
I would like to re-open this question specifically for the HT version of the part. I need a reasonable and available part (i.e. not the TPS7H1201-HT) and would like to understand what limits the TPS76901-HT from use at 5.0 Volts.
Thank you in advance for your thoughts.
