REG104FA-5/500 Description

Short technical summary and product information.

The Texas Instruments REG104FA-5/500 is a 1-A, 15-V low-dropout (LDO) voltage regulator designed for applications requiring stable power with minimal noise and fast response. It boasts an ultra-low dropout voltage of 230mV typical at 1A output current, contributing to high efficiency.

 

This regulator supports an input voltage range from 2.7V to 15V and provides fixed output options including 2.5V, 3V, 3.3V, and 5V, as well as an adjustable output option. The output current capability is up to 1A. Key electrical characteristics include very low noise (33µVrms) and high accuracy (±2% maximum).

 

The REG104FA-5/500 operates within a temperature range of -40°C to 85°C. It is available in small surface-mount packages such as SOT-223 and TO-263, making it suitable for space-constrained designs. The device features an enable pin for power control and thermal protection.

 

Applications for this LDO include portable communication devices, battery-powered equipment, modems, bar-code scanners, and backup power supplies where efficient and clean power regulation is essential.
