TPS79425DGNT Description

Short technical summary and product information.

The Texas Instruments TPS79425DGNT is a member of the TPS794xx family of ultralow-noise, high-PSRR, fast, RF, 250mA low-dropout linear voltage regulators. This device provides a stable 2.5V fixed output voltage and can supply up to 250mA of current. It is designed for noise-sensitive analog applications, offering excellent line and load transient responses.

 

The regulator features ultralow noise (32 µVrms for the TPS79428 variant) and high PSRR (60 dB at 10 kHz), making it suitable for RF applications like VCOs and receivers, as well as ADCs and audio components. It has a fast start-up time of approximately 50 µs and a very low dropout voltage of 155 mV at full load. The device is stable with a small 2.2 µF ceramic capacitor on the output.

 

Available in an 8-MSOP PowerPAD package, the TPS79425DGNT is designed for surface mounting. It includes an Enable (EN) control feature and protection against over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The typical quiescent current is 170 µA, which can be reduced to less than 1 µA in standby mode.
