Efficiency up to 95%
Temperature range: -40°C ~ +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 also
be used to convert a positive voltage into
a negative voltage.
Only two extra capacitors are required.
Input voltage range can be lower than the
output voltage for higher output voltages
RoHS Compliance |
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 of
up 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. |
