Hi
I am using a TPS54231 with a 12 volt battery input and an output of 5 volts. This regulator powers a cellular radio that draws a large turn on current spike - 4 Amps for about a milli second.
Will the TPS54231 stay regulation when this spike hits.?
As the battery discharges will the TPS54231 stay in regulation when the input voltage drops to 5 volts due to the battery's internal impedance.
I will appreciate any comments.
Thanks
