Hi guys, i have a problem with power sequencing please help me the problem is , i have DSP processor have three voltages 1.05(core), 1.8(IO), and 1.8(DDR2 controller) i want to generate 1.8V for IOs and DDR2 controller from one regulator the problem is in sequencing between IOs and controller , IOs must power up before DDR2 controller , how i can do this without drop in power (1.8)
thanks barry for ur reply , but i don't want do use two regulators because i have no size for this but i can use MOSFET switch with delayed turn on as u said , but can i do this without drop in power (1.8)? i mean for delay
