With TSRN-1 series trough hole version and TSRN-1SM series SMD-version, TRACOPOWER launches a high efficiency alternative to common positive and negative 3-terminal linear voltage regulators (LM78xx and LM79xx)
They provide ultra wide input ranges up to 42 VDC. The trough hole version comprises nine models which have a fixed output voltage from 1.5 up to 15 VDC while the five models of the SMD version have an adjustable output, those cover the full range of 1.2 up to 15 VDC. All regulators can be used for positive and negative output voltage circuits. The trough hole version models are drop-in replacements for inefficient 78xx / 79xx linear regulators and they are available with straight or angular pins.
These switching regulators have significant advantages over linear regulators, they have a better output voltage accuracy, a lower standby current, much wider input range and they can be operated without external capacitors. With the very high efficiency of up to 95% they don’t need a heat sink or chassis contact. The SMD version models can be operated at full load up to 55°C and the trough hole version models up to 70°C ambient temperature. With some derating they can be used at an ambient temperature of up to 85°C. The high efficiency, low standby power consumption and remote On/Off function (for SMD version) make these regulators an ideal solution for energy sensitive applications.
