3.3 Operating Principles of Low Saturation Types
All of the power supply ICs discussed so far use Darlington connected NPN type transistors in the output stage.
Therefore, the voltage difference between input and output that is needed to operate these power supply ICs cannot
be lower than the voltage between the base and emitter of the Darlington connected output stage transistor (0.7 V
×
2 = 1.4 V). A low saturation type power supply IC makes it possible to operate with a small voltage difference
between input and output by using a PNP transistor as the output stage transistor (refer to Figure 3-7).

Configurations other than this are nearly identical to a general power supply IC.
