TPS79433DGNT Description

Short technical summary and product information.

The Texas Instruments TPS79433DGNT is a 250mA low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It provides a stable 3.3V output with a very low dropout voltage of 155mV at full load. The device features ultralow noise (32 µVrms) and high power-supply rejection ratio (PSRR), making it suitable for RF electronics, audio components, and portable devices.

 

Key electrical characteristics include a wide input voltage range from 2.7V to 5.5V and a typical quiescent current of 170 µA. The TPS79433DGNT is stable with a small 2.2 µF ceramic capacitor on the output and offers fast start-up times of approximately 50 µs. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

This regulator is available in an 8-HVSSOP package, designed for surface mounting. Its small footprint and low thermal resistance make it suitable for space-constrained designs. The device also features an enable pin for control.

 

Applications benefiting from its performance include wireless communication modules, portable RF electronics, ADCs, and audio circuits where low noise and high PSRR are critical.
