DESCRIPTION The LD29150 is a high current, high accuracy,
low-dropout voltage regulator series. These
regulators feature 400mV dropout voltage and
very low ground current. Designed for high current
loads, these devices are also used in lower
current, extremely low dropout-critical systems,
where their tiny dropout voltage and ground
current values are important attributes. Typical
applications are in Power supply switching post
regulation, Series power supply for monitors,
Series power supply for VCRs and TVs, Computer
Systems and Battery powered systems.
