LD29080
800 mA fixed and adjustable output very low drop voltage regulator
Datasheet
-
production data
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
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.

Note: 1 Guaranteed by design.
2 Dropout voltage is defined as the input-to-output differential when the output voltage drops
to 99% of its nominal value with V
O
+ 1 V applied to V
I
.
3 Reference voltage is measured between output and GND pins, with ADJ PIN tied to V
O
.
4 In order to avoid any output voltage rise within the whole operating temperature range, due
to output leakage current, a minimum load current of 2 mA is required.
