TPS79433DCQG4 Description

Short technical summary and product information.

The TPS79433DCQG4 from Texas Instruments is a 250mA low-dropout (LDO) linear voltage regulator. It provides a stable 3.3V fixed output voltage and is designed for applications requiring high power-supply rejection ratio (PSRR) and low noise.

 

Key electrical specifications include a maximum input voltage of 5.5V, a maximum output current of 250mA, and a low dropout voltage of 0.2V at 250mA. The device features a quiescent current of 220µA and includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO). It also offers an enable control feature.

 

This regulator is suitable for noise-sensitive analog components and RF applications. It is available in a surface-mount SOT-223-6 package, designed for efficient thermal management and ease of integration into compact electronic designs.
