Post Regulator Family
Advantages by Combining DC/DC
& Linear Post Regulators

Less power dissipation than linear regulator only
based solutions

Modular solution by using discrete ICs
– One simple-single-output DC/DC (ex: 3.3 to 10V)
– Other voltages generated by discrete post regulators
(1.8V, 3.3V, etc.)

Very reasonable alternative to lower system cost

Stand-alone DC/DC with discrete post regulators as
alternative to highly integrated system IC
