APPLICATIONS INFORMATION

curve shows power dissipation with no load.

When operated within its speciﬁed limits of VIN = 13.2V

and sourcing 5mA, the LTC6652-2.5 consumes just under

60mW at room temperature. At 125°C the quiescent cur-

rent will be slightly higher and the power consumption

increases to just over 60mW. The power-derating curve

in Figure 16 shows the LTC6652-2.5 can safely dissipate

125mW at 125°C about half the maximum power con-

sumption of the package.
