in Fig. 66-5. IC1 acts as a power buffer. The LT1027 forces the output of V0ut and ground to be 5 V. The RC damper (50 and 0.1 ¥) provides loop stability. The output might oscillate if low ESR capacitors are connected to it, so use aluminum electrolytic or tantalum capacitors instead of ceramic or mylar.
