DESCRIPTION
The LD29300 is a high current, high accuracy, low-dropout voltage regulator series. T hes e regulators feature 400mV dropout voltage and very low ground current. Designed forhigh current loads, these devices are also used in lower current, ext remel y low dropout-critical systems, where their tiny dropout voltage and ground current val ues are important attributes. Typical applications are in Power supp ly switching post regulation, Series power supply for monitors, Series power supplyforVCRs and TVs, Computer Systems and Battery powered systems.
