3A VERY LOW DROP VOLTAGE REGULATOR
1/12December 2002 VERY LOW DROPOUT VOLTAGE (TYP. 0.4 3A) GUARANTEED OUTPUT CURRENT UP TO FIXED VOLTAGE WITH ±1% TOLLERANCE 25°C INTERNAL CURRENT AND THERMAL LIMIT
DESCRIPTIONThe LD29300isa high current, high accuracy,
low-dropout voltage regulators series. These
regulators feature 400mV dropout voltages and
very low ground current. Designedfor high current
loads, these devices also find applicationsin lower
current, extremely low dropout-critical systems,
where their tiny dropout voltage and ground
current values are important attributes. Typical
application arein Power supply switching post
regulation, Series power supply for monitor,
Series power supplyfor VCRs and TVs, Computer
Systems and Battery powered systems.
