> The 450 mA at 0.15 ohm

This d/s says 0.2R @ 4.5V, 0.3R @ 2.5V


Take a look at Figures 2 and 4, you might find that Ron is higher than
you planned for

If I'm asssuming correctly, quick look, and the normalised Ron is *1.1
@ 3.5V and 0.5A, then that would mean actual Ron in circuit is 0.33R,
so you'd be losing 0.450A * 0.33R = 0.15V. If so, that puts the voltage
available for the Rabbit at 3.15V

Can you bump up the regulator output a little ?
