We used a linear regulator to supply a fixed volt- age to the power amplifier final stage in a portable cellular phone. This resulted in longer talk times with Lithium Ion batteries, and reduces the power dissipation requirements of portable cellular phone power amplifier final device packages. Adding a lin- ear regulator to the radio adds 5 to 10 minutes of talk time when a Lithium Ion battery is used.
