Features
Efficiency up to 95%,Non isolated,
no need for heatsinks
Pin-out compatible with LM78XX Linears
Low profile( L*W*H=11.5*8.5*17.5mm)
Wide input range.(4.75V ~ 18V)
Short circuit protection, Thermal shutdown
Non standard outputs available as specials
between 1.5V ~ 6.5V
Low ripple and noise
“L” Version with 90° pins
Description
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.

Optional Protection Circuit
Optional Protection 1:
Optional Protection 2:
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.
The diode can either be fitted
across the device if the source is
low impedance or fitted in series
with the output (recommended).
