REG113NA-5/3K Description

Short technical summary and product information.

The Texas Instruments REG113NA-5/3K is a 400mA, 5V low-dropout (LDO) linear voltage regulator designed for various applications. It features a low dropout voltage of 250mV typical at 400mA and does not require an output capacitor for stability, simplifying circuit design.

 

Key electrical characteristics include a high accuracy of ±1.5% maximum, very low noise at 28 µVrms, and fast transient response. The regulator operates from an input voltage up to 10V and provides a stable 5V output. Protection features include over current and over temperature shutdown.

 

This device is available in small surface-mount packages, specifically the SOT-23-5 (DBV). The operating temperature range is -40°C to 85°C, making it suitable for a wide array of portable and battery-powered equipment.

 

Applications for the REG113NA-5/3K include portable communication devices, battery-powered equipment, personal digital assistants, modems, bar-code scanners, and backup power supplies.
