APPLICATIONS
The M78xx05 Series high efficiency
switching regulators are ideally suited to
replace LM78xx linear regulators and are
pin compatible. The efficiency of up to 96%
means that very little energy is wasted as
heat, eliminating the need for heat sinks and
conserving board space.
If Input voltage above specified may cause permanent damage to the device
