R-78C-1.0 Datasheet, PDF (1/2 Pages) Recom International Power – 1.0 AMP SIP3 Single Output

Features
● Efficiency up to 96%, no need for heatsinks!
● Pin-out compatible with LM78XX Linear Regs.
● Low profile (L*W*H=11.6*8.5*10.4mm)
● Wide input range (5V ~ 42V)
● Short circuit protection, thermal shutdown
● Non-standard outputs available as specials
● Low ripple and noise
● See Innoline App Notes for use as a positive-to-
negative inverter (alternative to 79xx regulator)
Description
The R-78Cxx-1.0 series switching regulators are ideally suited to replace 1 Amp 78xx linear regulators and are pin
compatible. Efficiencies of up to 96% means that very little energy is wasted as heat and the high input voltage is a
useful feature.
