Features
Switching
Regulator
• Efficiency up to 94%, no need for heatsinks
• Pin compatible with LM78XX linears
• Low profile (L/W/H=11.5 x 7.55 x 10.2mm)
• Wide input range
• Short circuit protection, thermal shutdown
• Low ripple and noise
• IEC/EN60950-1 certified
DC/DC Converter
R-78-1.0
Description
The R-78xx-1.0 series switching regulators are ideally suited to replace 1 Amp 78xx linear regulators
and are pin compatible. Efficiencies of up to 94% mean that very little energy is wasted as heat so there
is no need for any heat sinks with their additional space and mounting costs.

+Vout
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).
