Typical performance

Figure 35. Adjustable output voltage with temperature compensation

VO = VXX (1+R2/R1) + VBE

Note:

Q2 is connected as a diode in order to compensate the variation of the Q1 VBE with the

temperature. C allows a slow rise time of the VO.

Figure 36. Light controllers (VOmin = VXX + VBE)

VO falls when the light goes up

VO rises when the light goes up
