ing a stable, low cost, and low power reference voltage in
portable equipment power supplies. Figure 36 shows how the
ADR291/
ADR292
ADR291 and ADR292 can be used in a voltage regulator that
not only has low output noise (as compared to switch mode
design) and low power, but also a very fast recovery after

possible.
