HOW TO INCREASE OUTPUT CURRENT OR OUTPUT VOLTAGE CAPABILITY

two or more ST662A devices; each one of them can supply 30mA. The figure 19 shows the electric

possible, you can place two different capacitors, each of them of half value, very close to the respective

integrated circuit.

Fig. 21 show the Output Current capability of the proposed circuit.

If an output voltage greater than 12V is required, it’s possible to realize the circuit of the following diagram

(figure 20). The relevant Output Current capability is shown in figure 22 in which is shown the output

voltage vs load current.
