R-78E5.0-1.0, Recom

The R-78E series is a switching regulator module that has been designed to offer all the advantages of a switching regulator (high efficiency, wide input range, accurate output voltage regulation) but with a low cost for production quantities. Due to the R-78Es high efficiency of up to 91% at an output voltage of 5V/1A at the output, no heat sink is required. The compact TO- 220 compatible SIP3 package measures only 11.6 x 8.5 x 10.4 mm, so it saves precious board space. The warranty is 3 years. Efficiency up to 91%, no need for heat sinks Pin-out compatible with LM78XX Linear Regs. Low profile (L*W*H=11.6*8.5*10.4mm) Wide input range (7V - 28V) Short Circuit Protection IEC/EN60950-1, Am2 Certified
