Overview

The TLV74311PDQNR3 is a low-dropout (LDO) linear voltage regulator designed for power-sensitive applications. It provides a fixed 1.1V output from an input voltage range of 1.4V to 5.5V, capable of delivering up to 300mA of current. Its compact 4-pin X2SON package makes it suitable for space-constrained designs.

Why Choose This Part

This LDO offers a low quiescent current of 34 uA and a very low shutdown current of 0.1 uA, which is crucial for extending battery life in portable devices. Its compact 1x1mm X2SON package minimizes board space. Integrated protection features like foldback overcurrent, overtemperature, and undervoltage lockout enhance system reliability.

Applications

Smartphones and Tablets
Providing stable power for various internal components due to its small size and low quiescent current.
Notebook and Desktop Computers
Regulating power for auxiliary rails or specific ICs within the system.
Portable Industrial and Consumer Products
Delivering reliable power in battery-powered devices where efficiency and compact size are critical.
WLAN and Other PC Add-On Cards
Supplying clean regulated voltage to sensitive wireless or peripheral integrated circuits.
Camera Modules
Ensuring stable power for image sensors and processing units in compact camera applications.
