TPS79401DGNT

The Texas Instruments TPS79401DGNT is a linear voltage regulator designed for applications requiring precise voltage control. It features an adjustable positive output and a maximum current rating of 250 mA. The device operates within a temperature range of -40°C to 125°C, making it suitable for various environmental conditions.

Key electrical characteristics include a voltage range of up to 5.5V and a low quiescent current of 220 µA. It also provides protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The high power-supply rejection ratio (PSRR) of 65dB to 40dB across a frequency range of 100Hz to 100kHz ensures stable performance in noisy power environments.

This regulator is available in an 8-HVSSOP package and is designed for surface mount applications. The exposed pad on the 8-TSSOP, 8-MSOP package enhances thermal performance. The device includes an enable control feature for power management.

Applications for the TPS79401DGNT include RF circuits, portable electronics, and other noise-sensitive systems where stable and clean power is critical. Its ultralow noise and fast start-up times contribute to reliable operation in demanding applications.
