Voltage for step-up regulator U3V16F15

Hi, I recently purchased a U3V16F15 voltage regulator to control a motor. I connected a 3v battery in, where it registered 3.19 v. When I checked the voltage out it only registers 4.5v. Any ideas why it’s not stepping up to the 15v it’s supposed to?


Nevermind my original question. After some additional testing, I determined there is too much resistance in the wire/ connectors between the battery and the voltage regulator. It can’t supply the necessary minimum voltage for the regulator to operate at startup.
