APPLICATION
The K78Uxx-500(L) series high efficiency switching regulators are ideally suited to replace LM78xx linear regulators and are pin compatible. It has ultra wide input voltage range, the efficiency ofup to 95% means that very little energy is wasted as heat so there is no need for any heatsinks with their additional space and mounting costs.
feature list
Efficiency up to 95%
Temperature range: -40°C to +85°C
No heat sink required
Pin-out compatible with LM78xx linears
Short circuit protection, Thermal shutdown
Low ripple and noise
SIP package
Industry standard pinout
MTBF>2,000,000 hours
The K78Uxx-500 series converters can alsobe used to convert a positive voltage intoa negative voltage.
Only two extra capacitors are required.
Input voltage range can be lower than theoutput voltage for higher output voltages
