Features
Switching
Regulator
Description
Efficiency up to 95%, no heatsinks required
Pin-out compatible with LM78XX linears
Low profile (L/W/H=11.5 x 8.5 x 17.5mm)
Wide input range
Short circuit protection, thermal shutdown
Low ripple and noise
„L“ version with 90° pins
DC/DC Converter
R-78B-1.5(L)
The R-78Bxx-1.5 series high efficiency switching regulators are ideally suited to replace 78xx
linear regulators and are pin compatible. The efficiency of up to 95% 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.
The L-Version with 90° pins allows direct replacement for laid-flat regulators where component height is
at a premium. Low ripple and noise figures and a short circuit input current of typically only 10mA round
off the specifications of this versatile converter series.
