REG113NA-2.5 Description

Short technical summary and product information.

The Texas Instruments REG113NA-2.5 is a 400mA, low-dropout (LDO) linear voltage regulator designed for various power management applications. It accepts an input voltage range from 2.7V to 10V and offers fixed output voltage options including 2.5V, 2.85V, 3.0V, 3.3V, and 5.0V, with other voltages available upon request.

 

Key electrical characteristics include a typical dropout voltage of 250mV at 400mA, ensuring high efficiency. The regulator features very low noise (28 µVrms) and high accuracy (±1.5% max). It also includes foldback overcurrent protection and thermal protection for enhanced reliability. The device supports peak output currents up to 500mA and offers fast transient response.

 

Designed with a CAP-FREE DMOS topology, the REG113NA-2.5 does not require an output capacitor for stability. It is available in small surface-mount packages such as SOT-23-5 and VSSOP-8, making it suitable for space-constrained designs. The quiescent current is typically 0.4mA when enabled and drops to 0.01µA when disabled.

 

This LDO regulator is well-suited for portable communication devices and battery-powered equipment where low power consumption and stable voltage regulation are critical.
