ElectronicsThe ULN2003 with Darlington Transistors SOP16 RoHS manufactured by Siproin Electronics is an integrated circuit that contains seven Darlington Transistors arranged in a $16 \text{-pin}$ small outline package (SOP) for use in motor controls, signal relays, level converters, and other applications that require a high voltage/current gain and low saturation. It can handle up to 500mA output current and features built-in overload and thermal protection, as well as being compliant with the EU RoHS Directive. It also has a low on-resistance, making it ideal for controlling high current applications with minimal voltage losses. The package of the part offers superior heat dissipation providing high reliability.
