LD29080_07 Datasheet, PDF (1/21 Pages) STMicroelectronics – 800mA Fixed and adjustable output very low drop voltage regulatorm

LD29080 series
800mA Fixed and adjustable output
very low drop voltage regulator
Features
■ Very low dropout voltage (Typ. 0.4 at 800mA)
■ Guaranteed output current up to 800mA
■ Fixed and adjustable output voltage (±1% at
25°C)
■ Internal current and thermal limit
■ Logic controlled electronic shutdown
Description
The LD29080 is a high current, high accuracy,
low-dropout voltage regulators series. These
regulators feature 400mV dropout voltages and
very low ground current. Designed for high
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
