We see from your search that you're looking for information on the term "LDO regulators",
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 Driver handles two displays with power to spare from
Linear Technology Corp, which we summarised at the time by saying "White LED driver incorporates dual LDO regulators for driving main and subsidiary LED displays and supplying low-voltage system rails".
A few weeks before,
we featured the news release Two regulators in one save space and cost from
Catalyst Semiconductor: "Each LDO in the CAT6221 has an independent enable pin and, combined, offer low quiescent current, 1% initial accuracy, and a very low typical dropout voltage".
In October 2007, we covered the news from Wolfson Microelectronics
concerning its WM8350
- take a look at Power management product cuts space required
which says: "The WM8350 is compatible with multimedia application processors and provides a highly integrated solution without compromising audio performance".
Take a look also at the news release from Power-One, Point-of-load module raises current level,
as well as LDOs are power-saving alternatives from Catalyst Semiconductor,
and LDOs tolerate 28V inputs from Torex Semiconductor.
