Hello,
I have a question on output voltage ramp up time and sequence for LP3891EMR-1.2. Vin = 3.3V, VBias = 5V and Vout = 1.2V. Ramp up time for 5V Bias voltage is 5us. Ramp up time for 3.3V is 3ms. (3.3V is generated from 5V using TPS54232D to achieve slow start).
What would be the ramp up time for 1.2V output? Also what would be the sequence between 3.3V input and 1.2V output from LP3891EMR-1.2. There is no specific sequence requirement, but ramp up time should be slow (min 200us) for both 3.3V and 1.2V.
Thank you.
Regards,
Sameer.
