APPLICATIONS
Output voltage accuracy
100% full load, input voltage
range
Upgraded K78xx-2000(L) series switching
regulators are ideal replacement for K78xx
linear regulators and LDOs. The efficiency of
up to 92% means that very little energy is
wasted as heat so there is no need for any
heat sinks with their additional space and
mounting costs. They are widely used in
industrial control, instrumentation, and electric
power applications.

Note:
1. C1 and C2 are required and should be fitted close to the converter pins.
2. The capacitance of C1and C2 sees external capacitor table, it can be increased properly if required, and tantalum or low ESR electrolytic
capacitors may also suffice.
3. No parallel connection or plug and play.
