Surely that is a low power circuit. I might even be able to sleep the chip when I'm currently pausing.
Art.
Regulator with max. 50mA output should be enough, even if you would like to have illumination on LCD. Realistic current consumption should be in a range of 20-30mA.
In case of illumination, then LED(s) must be PWM controlled (HPWM or similar).
