R-78-1.0 Datasheet, PDF (1/3 Pages) Recom International Power – 1.0 AMP SIP3 Single Output
vFeatures
● Efficiency up to 94%, no need for heatsinks!
● Pin-out compatible with LM78XX Linear Regs.
● Low profile (L*W*H=11.5*7.5*10.2mm)
● Wide input range (4.75V ~ 18V)
● Short circuit protection, thermal shutdown
● Non-standard outputs available as specials
● Low ripple and noise
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 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.
