R-78B-1.0 Datasheet, PDF (1/4 Pages) Recom International Power – 1.0 AMP SIP3 Single Output
Features
● Efficiency up to 97%,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 ~ 34V)
● Short circuit protection, Thermal shutdown
● Non standard outputs available as specials
between 1.5V ~15V
● Low ripple and noise
● “L” version with 90° pins
● See Innoline Application Notes for use as an
inverter (alternative to LM79xx Linear)
Description
The R-78Bxx-1.0 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.
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.
