Product overview

Description

The LD29080 is a medium current, high accuracy, low-dropout voltage regulators series. These regulators feature 400 mV dropout voltage and very low ground current. Designed for medium current loads, these devices also find applications in lower current, extremely low dropout-critical systems, where their tiny dropout voltage and ground current values are important attributes. Typical application 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.
  • All features

    • Very low dropout voltage (typ. 0.4 at 800 mA)
    • Guaranteed output current up to 800 mA
    • Fixed and adjustable output voltage (± 1 % at 25 °C)
    • Internal current and thermal limit
    • Logic controlled electronic shutdown
