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.

Note:
1. The regulator proposed to establish the input voltage by soft-start, no
plug and play, if the input voltage changes from low voltage to high voltage
abruptly, the regulator might be damaged.
2. If the applications is high-voltage input, the regulator must add an
external capacitor C1(≤47μF/100V),to prevent voltage spikes caused by
damage to the module.

2. If further filtering is required, please add components as per the above circuit(We
recommend not to add components), if request, please make sure the capacitors C1
≤47μF,C2≤10μF more close to the back-grade regulator.

Note:
1. The load shouldn't be less than 10%, and the output external capacitor should not be too large (recommend <10μF), otherwise ripple will increase
dramatically.
2.Operation under 10% load will not damage the converter; However, they may not meet all specification listed
3.All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4.In this datasheet, all the test methods of indications are based on corporate standards.
