DESCRIPTION

The LD29080 is a high current, high accuracy,

low-dropout voltage regulators series. These

regulators feature 400mV dropout voltages and

very low ground current. Designed for high current

loads, these devices also find applications in lower

current, extremely low dropout-critical systems,

where their tiny dropout voltage and ground

current values are important attributes. Typical

application 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.
