2A Switching Regulator

The RECOM R-78K-2.0 series is a cost-efficient and popular drop-in replacement for through-hole ‘78 series’ three-terminal linear regulators. The parts offer 2A-rated output and dramatically improved efficiency over linear types, eliminating heatsinking and its associated costs, while freeing up valuable board space.

The series is now available with 90-degree, pre-formed, through-hole pins for horizontal mounting where a low profile is preferred. Designated R-78K-2.0(L), the series includes fixed outputs of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V, 9V, 12V, and 15V, all with an input voltage range up to a maximum of 36V.

The R-78K-2.0(L) series has a maximum case temperature of +110°C, allowing an operation to +90°C ambient for some variants without derating, dependent on the input voltage.

Input under-voltage and short-circuit protection is provided, and the parts are certified to IEC/EN 62368-1 3rd edition.

 “The R-78K-2.0 series now has even wider application with the formed lead option, useful for horizontal mounting when board height is restricted” comments Matthew Dauterive, DC/DC product manager of RECOM.

Parts include a three-year warranty, and samples and OEM pricing are available from all authorized distributors, or directly from RECOM.
