TP78XX-2 series switching regulators are ideal replacement for TP78xx linear regulators and LDOs. The efficiency of up to 92% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. They are widely used in industrial control, instrumentation, and electric power applications.
