3A VERY LOW DROP VOLTAGE REGULATOR
1/17June 2003 VERY LOW DROPOUT VOLTAGE (TYP. 0.4 3A) GUARANTEED OUTPUT CURRENT UP TO FIXED VOLTAGE WITH ±1% TOLERANCE 25°C INTERNAL CURRENT AND THERMAL LIMIT LOGIC CONTROLLED ELECTRONIC
SHUTDOWN AVAILABLEIN PPAK
DESCRIPTIONThe LD29300isa high current, high accuracy,
low-dropout voltage regulator series. These
regulators feature 400mV dropout voltage and
very low ground current. Designedfor 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 arein Power supply switching post
regulation, Series power supply for monitors,
Series power supplyfor VCRs and TVs, Computer
Systems and Battery powered systems.
