R-78E-0.5

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 95% no heat-sink is required.

The compact TO-220 compatible SIP3 package measures only 11.6 x 8.5 x 10.4mm, so it saves

precious board space.

Notes:

Note3: recommend to use with more than 2% load, if not, the ripple of the product may exceeds the

speciﬁcation, but doesn’t affect the reliability of the product

Note4: Measurements are made with a 100nF MLCC across output (low ESR)

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
