The ULN2003 is a very versatile integrated circuit, internally composed of 7 identical drivers
The ULN2003 is a very versatile integrated circuit, internally composed of 7 identical and independent drivers, which allow to control relays, small DC motors, stepper motors, low voltage lights or LED strips with a microcontroller.
Each driver is made up of two transistors in Darlington configuration. The Darlington configuration, devised by Sidney Darlington in 1953, consists of connecting two bipolar transistors in cascade, thus obtaining a very high gain because the gain of each of the two transistors is multiplied. Thanks to this, we can control loads of a certain power with very small inrush currents.

The Darlington configuration is not without its flaws as we will see below. An NPN transistor of universal use begins to conduct when we apply a voltage of approximately 0.6V to its base. If we apply a small current to it, we can bring it to saturation, with a very low voltage between collector and emitter (VCE), for example, in the case of BC337, between 0.2V and 0.5V (to obtain a perfect switch you should be 0V).
In a Darlington pair, the input voltage will be double with respect to 0.6V because the base voltages of both transistors are added as we can see in the figure. The voltage drop across the output transistor will also be greater because it will be the sum of the saturation voltage of the first transistor + the base-emitter voltage of the output transistor.
