Figure P2.7 shows how a pnp BJT can boost the output current capability of an op amp when it comes to sinking current from the load (as opposed to sourcing current to the load, as discussed in the text). Assuming the BJT has F 5 80 and an E-B junction voltage drop of 0.8 V, fi nd the current and voltage at each of the BJT terminals if IL 5 500 mA. What is the voltage and current required of the op amp’s output?
