Features
Description
The LD29080xx is a high current, high accuracy,
low-dropout voltage regulators series. These
regulators feature 400 mV 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.
