OKI-78SR datasheet



Fabricated on a 0.41 by 0.65 inch (10.4 by 16.5 mm) Single Inline Package (SIP) module, the OKI-
78SR series are non-isolated switching regulator (SR) DC/DC power converters for embedded applications.

The fixed single output converters offer both tight regulation and high effi ciency directly
at the power usage site and are a direct plug-in replacement for TO-220 package 78xx series linear regulators. Typically, no extra outside components are required.


1. Ultra wide 7 to 36 VDC input range

2. Fixed Outputs of 3.3 or 5 VDC up to 1.5 Amps

3. Vertical or horizontal SIP-mount, small footprint package

4. “No heat sink” direct replacement for 3-termina

5. 78xx-series linear regulators

6. High effi ciency with no external components

7. Short circuit protection

8. Outstanding thermal derating performance

9. UL/EN/IEC 60950-1, 2nd Edition safety approvals
