REG113-3.3 Description

Short technical summary and product information.

The Texas Instruments REG113-3.3 is a 400mA, 10V low-dropout (LDO) linear voltage regulator designed for efficient power management in portable applications. It provides a stable output voltage with a minimum of 2.5V and a maximum of 5V, with specific fixed output options including 2.5V, 2.85V, 3.0V, 3.3V, and 5.0V. The device boasts a low dropout voltage of 250mV typical at 400mA, enabling operation with lower input voltages and improving efficiency.

Key electrical characteristics include a typical quiescent current of 0.4mA when enabled and 0.01µA when disabled, contributing to power savings in battery-operated devices. It offers a typical noise level of 28µVrms and a PSRR of 28dB at 100KHz, ensuring clean power delivery. The regulator includes features such as enable, foldback overcurrent protection, and thermal protection for enhanced reliability.

Available in compact SOT-23-5 and VSSOP-8 surface-mount packages, the REG113-3.3 is suitable for space-constrained designs. Its operating temperature range is -40°C to 85°C, making it robust for various environmental conditions. The CAP-FREE DMOS topology means an output capacitor is not required for stability, simplifying circuit design.

Applications for the REG113-3.3 include portable communication devices and other battery-powered equipment where efficient and stable voltage regulation is critical.
