We see from your search that you're looking for information on the term "LDO 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 LDO regulator provides high start-up current from
Nu Horizons Electronics Corp, which we summarised at the time by saying "Micrel's MIC68200 is capable of sourcing 2A of current for start-up and operates from an input voltage of 1.65 to 5.5V".
A few weeks before,
we featured the news release Power management devices cut consumption from
Oki Electric: "LDO provides power consumption of 50-100nA in standby mode and 3-12uA in no-load mode - an 80-90% reduction in power consumption compared with the industry standard".
In October 2007, we covered the news from Catalyst Semiconductor
concerning its CAT6221
- take a look at Two regulators in one save space and cost
which says: "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".
Take a look also at the news release from Catalyst Semiconductor, LDOs are power-saving alternatives,
as well as Power supply chip is smart SIM option from Linear Technology Corp,
and Tiny LDO is a speedy turn-on from Catalyst Semiconductor.
