TPS79433DGNR Description

Short technical summary and product information.

The Texas Instruments TPS79433DGNR is a 250mA low-dropout (LDO) linear voltage regulator featuring ultralow noise, high power-supply rejection ratio (PSRR), and fast start-up times. It provides a fixed 3.3V output and is stable with a small 2.2µF ceramic capacitor on the output.

 

This regulator is ideal for noise-sensitive analog components and RF electronics, benefiting from its high PSRR (60dB at 10kHz) and low noise (32 µVrms). The device offers a low dropout voltage of 155mV at a full load of 250mA and operates within a temperature range of -40°C to 125°C.

 

The TPS79433DGNR is available in an 8-HVSSOP package, suitable for surface mounting. It includes enable control and protection features such as over current, over temperature, reverse polarity, and undervoltage lockout (UVLO).

 

Key electrical characteristics include an input voltage range of 2.7V to 5.5V and a quiescent current of 0.17mA typical. The regulator's excellent load and line transient response make it suitable for demanding applications.
