Datasheet

COO (Country of Origin):: CN

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.

7-36Vin (3.3 & 5Vout), 15-36Vin (12Vout)
Fixed Output: 3.3 or 5V @ 1.5A or 12V @ 1.0A
Vertical SIP or horizontal mount, small footprint
package
No heat sink” direct replacement for 3-terminal
78xx-series linear regulators
High efﬁciency with no external components
Short circuit protection
Outstanding thermal derating performance
