0.5 AMP SMD Single Output

Description
The R-78Axx-0.5SMD series high efficiency switching regulators are ideally suited to pick-and-place mass production. The efficiency of up to 97% means that very little energy is wasted as heat. The additional features of remote on/off control and adjustable output voltages will find many uses in the Battery-powered, Industrial, Medical and Automotive markets. Low ripple and noise figures and a shutdown input current of typically only 20uA round off the specifications of this versatile SMD converter series.

Features
● Efficiency up to 97%,Non isolated, no need for heatsinks
● SMD Package
● Adjustable Output Voltage
● Wide input range.(4.75V ~ 34V)
● Short circuit protection, Thermal shutdown
● Remote On/Off Control
● UL94V-0 Package Material
● Very Low Shutdown Current
● See Positive-to Negative Converter
   Application Note for use as a voltage
   inverter (alternative to LM79xx Linear)
