TP78Lxx-1.5 Series Wide Input Non-Isolated & Regulated Single Output TP78LXX-1.5 series switching regulators are ideal replacement for TP78xx linear regulators and LDOs. The efficiency of up to 95% 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. ROHS Compliant Wide input non-isolated, regulated single output Efficiency up to 95% Short circuit protection, Thermal shutdown Temperature range: -40°C ~ +85°C Low ripple noise SIP package No heat sink required Industry standard pinout
