This is the top of the chip. The top-left pin is almost always Pin 1. Count down the left side and then over to the bottom right side and back up. 4700 Ohms or 4.7KOhms - UK, Europeans and Australia use this method of labeling. Find a voltage regulator with the specs you need.
People often ask if they can use a voltage ladder to drop the voltage.
I wouldn't recommend this as the ladder will usually draw a large current and it is not simple to predict what your circuit will draw and thus the selection of resistors is hard. Another way to drop voltage is to use diodes. If you place a diode inline with the circuit, it will drop the voltage by .7V for silicon diodes. If you want to drop a 5V battery to 2.9V, use 3 silicon diodes in a row. Download and run the BasicElectronics.
