The Recom Power R-78E3.3-1.0 is a high-efficiency switching regulator module designed as a pin-compatible replacement for LM78XX linear regulators. It accepts a wide input voltage range of 7V to 28V and provides a regulated 3.3V output at up to 1A (3.3W).
With a typical efficiency of 91% at minimum input voltage and full load, the R-78E3.3-1.0 requires no heatsink, saving board space and reducing thermal management complexity. The module operates at a switching frequency of 330kHz and features short circuit protection with automatic recovery.
The R-78E3.3-1.0 is housed in a compact 3-SIP through-hole package measuring 11.6 x 8.5 x 10.4 mm. It is rated for operation from -40°C to +85°C and is suitable for commercial ITE applications. The module is RoHS2+ and REACH compliant.
