Description
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-78E’s 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.
Notes:
Note1: Efficiency is tested at full load at +25°C ambient
Note2: Max. Cap Load is tested by nominal input and full resistive load
Notes:
Note3: R-78E12-1.0/X9 is available with epoxy potting only.
