  • 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.

    Key Features

    • Very low dropout voltage (typ. 0.4 V at 3 A)
    • High accuracy: ±1% @ 25°C
    • Guaranteed output current up to 3 A
    • Internal current and thermal limit
    • Logic controlled electronic shutdown
