The TSR 2N and TSR 3N are two step-down switching regulator series (2A and 3A) and a drop-in replacement for any TO-220 package linear regulators. These series come in a compact SIP-3 plastic package and complement our new generation of POL converters focusing strongly on a cost-efficient design while also improving on critical electrical specifications. Output voltages are available between 1.2 and 15VDC. Depending on the model, the efficient design allows full load operation up to +95°C ambient temperature (at nominal Vin) without the need of any heat sink or forced cooling. The TSR 2N and TSR 3N switching regulators provide other significant features like short circuit protection, current limitation and under voltage lockout. Overall, they offer a broad application range in many environments and are especially suited for high volume projects where the series will help to reduce production cost by delivering not only a highly cost efficient but also reliable solution.
