Fixed Output: 3.3 or 5V @ 1.5A or 12V @ 1.0A 78SR-E series are non-isolated switching Based on ?xed-frequency buck switching  Vertical SIP or horizontal mount, small footprint, regulator (SR) DC-DC power converters for topology, the high ef?ciency means very low heat in an Encapsulated package embedded applications. The ?xed single output and little electrical noise, requiring no external  converters offer both tight regulation and high components. The 3.3 and 5Vout models have an ?No heat sink? direct replacement for 3-terminal ef?ciency directly at the power usage site and are ultra wide input range of 7 to 36 Volts DC and the 78xx-series linear regulators a direct plug-in replacement for TO-220 package 12Vout model has an input voltage range of 15 to  High ef?ciency with no external components 78xx series linear regulators. Typically, no extra 36V.  Short circuit protection outside components are required. Protection features include short circuit  Outstanding thermal derating performance current limit protection. The OKI-78SR-E is  UL/EN/IEC 60950-1, 2nd Edition safety approvals designed to meet all standards approvals. RoHS-6 (no lead) hazardous material compliance is speci?ed as standard.
