Honored ContributorMax10 Single supply internal voltage regulator
Hi
MAX[SUP]®[/SUP] 10 single-supply devices only need either a 3.0- or 3.3-V external power supply. The external power supply serves as an input to the MAX[SUP]®[/SUP] 10 device VCC_ONE and VCCA power pins. This external power supply is then regulated by an internal voltage regulator in the MAX[SUP]®[/SUP] 10 single-supply device to 1.2 V. The 1.2-V voltage level is required by core logic operation. My question is: What type of voltage regulator is used ? Linear regulator ? Switching regulator? Thanks4 Replies

Mybe you may follow the Altera example on your application. The avaluation kit for 10M08 uses this switching regulator:

Let me clarify my previous response. The external power supply (3.0 or 3.3V) may be switching or linear, your choice. The internal voltage regulator is almost certainly linear.
