www.ti.comhighest (differences between the types is detailed in the following sections). Increased ground pin current is undesirable since it is "wasted" current, in that it ... Standard regulator, the pass device is a network composed of one PNP and two NPN transistors, which means the total current gain is extremely high (>300).

Transistors: Bipolar Junction Transistors (BJT)
ocw.mit.eduThe npn BJT and the pnp BJT. The BJT symbols and their corresponding block diagrams are shown on Figure 1. The BJT is fabricated with three separately doped regions. The npn device has one p region between two n regions and the pnp device has one n region between two p regions. The BJT has two junctions (boundaries between the n and the p regions).
