LD29300 series
3A, Very low drop voltage regulators
Features
■ Very low dropout voltage (Typ. 0.4 at 3A)
■ Guaranteed output current up to 3A
■ Fixed voltage with ±1% tolerance at 25°C
■ Internal current and thermal limit
■ Logic controlled electronic shutdown available

Description
The LD29300 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.
