◆ Pin-out compatible with WRN78XX linear
◆ Low profile (L*W*H=11.6×10.2×7.5mm)
◆ Very wide input range(5V~42V)
◆ Short circuit protection,Thermal Shutdown
◆ Non standard outputs available as specials
◆ Low ripple and noise
MODEL SELECTION
WRN78^①V^②05^③-1000^④
①Product Series ②Very wide input range
③Output Voltage ④Output Current
DESCRIPTION
The WRN78Vxx-1000 Series switching regulators are
ideally suited to replace 1Amp WRN78xx linear regulators
and are pin compatible. The efficiency of up to 96%
means that very little energy is wasted as heat and the
high input Voltage is a useful feature.
