TSRN-1 Series 1A step-down switching regulators with a wide input voltage range of up to 42 Vdc and a high efficiency of up to 95% which allows full load operation without the need for a heatsink or forced air cooling. These TSRN-1 Series 1A step-down switching regulators are suitable for positive and negative output circuits (please refer to table for additional data). Excellent line and load regulation and a low standby current makes these TSRN-1 switching regulators ideal for use in energy sensitive applications. Input voltage range up to 42 VDC. Built in filter capacitors. No heat-sink required. Over-temperature and short circuit protection. Low standby current: 1 mA for <= 3.3 Vdc output models, 3 mA for >= 5.0 Vdc ouput models. SIP package fits existing TO-220 footprint. Pin compatible with LMxx linear regulators Input Voltage = 10.5 - 27 V dc, 10.5 - 42 V dc Output Voltage = ±9V dc Number of Outputs = 1 Output Current = 1 A, 300 mA Mounting Type = Through Hole Package = SIP Minimum Temperature = -40°C Maximum Temperature = +85°C Efficiency = 82 %, 88 % MTBF = 6000000h Delivery on production packaging - Tube.
