Product Details
Fabricated on a 0.41 x 0.65 inch (10.4 x 16.5 mm) Single Inline Package (SIP) module, the OKI-78SR series are non-isolated switching regulatorSR) DC-DC power converters for embedded applications. The fixed single output converters offerboth tight regulation and high efficiency directly at the power usage site and are a direct plug-ineplacement for TO-220 package 78xx series linear regulators. Typically, no extra outside components are required.
