We see from your search that you're looking for information on the term "Linear regulator",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Switching regulator is cool alternative to linear from
Linear Technology Corp, which we summarised at the time by saying "Complete DC/DC module includes a DC/DC controller IC, power switches, inductor, compensation circuitry and input and output bypass capacitors".
A few weeks before,
we featured the news release LDO goes even lower for handheld efficiency from
Micrel: "Ultralow dropout and low input voltage feature combination allows high efficiency power conversion from low voltage supply rails commonly used in handhelds".
In November 2007, we covered the news from Allegro MicroSystems Europe
concerning its A4401
- take a look at PSU controller targets automotive displays
which says: "Automotive-grade quasiresonant discontinuous flyback convertor control IC provides all the necessary control functions for driving a vacuum fluorescent display".
Take a look also at the news release from Linear Technology Corp, Regulator protects against spikes and hot swapping,
as well as LDO provides portable flexibility from Texas Instruments (April 2006-),
and Pulsewidth modulator closes feedback loops from Microchip Technology.
