TPS79430DGNR Description

Short technical summary and product information.

The Texas Instruments TPS79430DGNR is a 250mA low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It provides a stable 3V output voltage with a low dropout voltage of 155mV at full load. The device features ultralow noise (32 µVrms) and high power-supply rejection ratio (PSRR) of up to 65dB at 100Hz, making it suitable for RF electronics, ADCs, and audio components.

 

Key electrical characteristics include an input voltage range of 2.7V to 5.5V and a quiescent current of 220µA typical. The TPS79430DGNR is stable with a minimum output capacitance of 2.2µF. It includes enable control and protection features such as over current, over temperature, and undervoltage lockout.

 

This regulator is available in an 8-HVSSOP package, also described as 8-TSSOP, 8-MSOP with an exposed pad. It is designed for surface mount applications. The device family offers both fixed and adjustable output versions, with fixed options including 1.8V, 2.5V, 2.8V, 3.3V, and 5.4V, in addition to the 3V output of this specific part.
