Powering an ADXL325 Accelerometer

The ADXL325 accelerometer is rated for 350 microamps of current at an input voltage range of 3-5 volts. What power source is suggested to provide this voltage and current? Using an AC-to-DC converter rated for 5 volts won't work because its output current is 100 mA (and at this current, I'm worried that the accelerometer will burn-out), so are batteries my only option?
