Description
The LD29300 is a high current, high accuracy,
low-dropout voltage regulator. This regulator
features 400 mV dropout voltage and very low
ground current. Designed for high current loads,
this device is also used in lower current,
extremely low dropout-critical systems, where its
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.
