Ir distance sensor and Servo motor

How much current can you source from an Arduino?

I am using an IR distance sensor and a servo. I want to know If i can power both of them from my Arduino UNO.

Servo motor http://www.sparkfun.com/products/9064

40ma per I/O pin. I know it works for the IR sensor, and its enough for the control signal on the servo, however the power line on the servo should be plugged into the 5v rail.
