Hello,
Do you believe that the MCP1703 (sot89) 5v regulator can deliver 5V to a circuit which is pulling zero amps through it? (not loading it at all?)
Figure 5 of the datasheet (fig 2-3) appears to suggest so.

Its just that im using it to supply a few CMOS chips and wonder if at start up, before much load current is being pulled, maybe the output is going over 7V sometimes, above the abs max's of the chips being supplied, (though scoping doesn't show this.)

According to the data sheet you should be OK, the device has internal load resistances to make up it's own voltage divider and no minimum load current is specified.

The only caution would be it's response to a step up voltage change at it's input which from the graph implies it could momentarily go as much as 0.1V 'over the top' but the transient is not present at power up and in any case would be curtailed by the output capacitor.

Brian.
