Other Parts Discussed in Thread: LM26480SQ-AAEV,
Hello,
When using the LM26480SQ-AAEV evaluation board and also in the implementation of my design, I observe the following:
Using an input voltage of 3.3V and with the ENLDOx tied directly to VINLDOx, so that the LDOs are enabled as soon as the input voltage is applied, I observe a delay of approximately 6 ms from the voltage level at ENLDOx reaching 2V to when the output of the corresponding LDO ramps up.
I wonder if there is an undocumented delay in the startup of the LDOs. Section 7.6 of the datasheet mentions that the Turn-on time (Ton) for the LDOs is typically 300 us.
I will appreciate some guidance.
Kind Regards,
Marco
