Linear Regulators in Portable Applications

Overview Advances in voltage-regulator design have helped to establish portable electronic products as the fastest-growing segment of the electronics industry. The demands for low cost, long battery life, and small size in this market are changing and rearranging the design priorities for power supplies. The result is a general rewrite of specifications for the latest generation of power-supply ICs.

Surprisingly, both switch-mode and linear voltage regulators have participated in this transformation. Despite the predominant use of switch-mode regulators in portable products, the linear regulator remains a viable contender. Advances in operating current, dropout voltage, noise, and packaging have made the modern linear regulator very different from the LM309s and µA7805s used for most designs in the past.
