REFERENCES AND LOW DROPOUT LINEAR REGULATORS
2.1
VOLTAGE REFERENCES AND
LOW DROPOUT LINEAR REGULATORS
Walt Jung
Reference circuits and linear regulators actually have much in common. In fact, the
latter could be functionally described as a reference circuit, but with greater current
(or power) output. Accordingly, almost all of the specifications of the two circuit
types have great commonality (even though the performance of references is usually
tighter with regard to drift, accuracy, etc.). This chapter is broadly divided into an
initial discussion on voltage references, followed by a concluding discussion on
linear regulators, with emphasis on their low dropout operation for highest power
efficiency.
