TRACOPOWER Switching Regulator, Through Hole, ±9V dc Output Voltage, 10.5 → 32 V dc, 10.5 → 42 V dc Input / 7553419

Part numbers: TSRN 1-xxxx have straight pins Part numbers: TSRN 1-xxxxA have angular pins MTBF: MIL-HDBK-217 @ +25°C Derating: 2.7 %/K above +70°C For input voltages higher then 36 Vdc an input capacitor 22 μF/ 50 V is required. 3. Traco 1A SIP Step Down Switching Regulator - TSRN-1 Series. 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
