no need for heatsinks
Pin-out compatible with LM78XX Linears
Very low profile( L*W*H=11.5*7.5*10.2 )
Wide input range.(4.75V ~ 32V)
Short circuit protection, Thermal shutdown
Non standard outputs available as specials
Low ripple and noise
UL94V-0 package material
EMC, Safety Certified
See Innoline Application Notes for use as an
inverter (alternative to LM79xx Linear)
Description
The R-78xx-Series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are
pin compatible. The efficiency of up to 97% means that very little energy is wasted as heat so there is no need for
any heat sinks with their additional space and mounting costs. Low ripple and noise figures and short circuit ,
overload and over-temperature protection round off the specifications of this versatile converter series.
This R-78xx-0.5 is fully certified to EN 55022 (Emissions), and EN55024 (Immunity) EMC Standards and for
IEC/EN-60950-1 + A2 Safety.

Optional Protection 1:
Add a blocking diode to Vout if
current can flow backwards into
the output, as this can damage
the converter when it is powered
down.
