A normal 555 like the NE555 will work with minimum supply voltage of 4.5. This is stated in the datasheet
http://www.555-timer-circuits.com/datasheets/ne555.pdf
If you need to go lower than that you should research the CMOS timer 7555. It has a voltage range of 3-16 volts and handles lower currents.

Hope that helps.

No 555 timer will output that much unless you use a buffer transistor.

If you can use 5 volts then I suggest using the NE555 with a TIP31 or equivalent buffer transistor.
