That is a regulator and your input voltage has to be higher than the output voltage. So use 2 batteries in series... + to - to + to - to gain 7-8 volts input.

Current @ 1.5 may be too low and cause overheating.
STMICROELECTRONICS|L7805C-V|IC, LINEAR VOLTAGE REGULATOR 5V | Newark.com

  • IC, LINEAR VOLTAGE REGULATOR 5V TO-220-3
  • Primary Input Voltage:10V
  • Output Voltage Fixed:5V
  • Dropout Voltage Vdo:2V
  • No. of Outputs:1
  • No. of Pins:3
  • Output Current:1.5A

If you want to use a single battery you could use a TI ptn04050c
