Upgraded K78XX-1500(L) series switching

regulators are ideal replacement for K78xx

linear regulators and LDOs. The efficiency

of up to 95% 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.

(Figure 2)

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.
