The TS78M15CP RO comes in a TO-220 package, which allows for easy mounting and effective heatsinking. It is a dependable linear voltage regulator suitable for many different applications. A heatsink is necessary for operation at higher current levels. The regulator can handle input voltages of up to 35V, with a typical dropout voltage around 2V, so the input voltage must be at least 17V to ensure proper regulation. The 'RO' suffix may denote RoHS compliance.
