TPS79433DCQ Description

Short technical summary and product information.

The Texas Instruments TPS79433DCQ is a 250mA low-dropout linear voltage regulator designed for applications requiring ultralow noise and high power-supply rejection ratio (PSRR). It provides a fixed 3.3V output voltage and is stable with a 2.2µF ceramic capacitor on the output. The device features a fast start-up time and excellent load and line transient responses.

 

Key electrical specifications include a maximum input voltage of 5.5V, a maximum dropout voltage of 0.2V at 250mA, and a quiescent current of 220µA. The PSRR is rated between 65dB and 40dB across a frequency range of 100Hz to 100kHz. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

This regulator is housed in a surface-mount SOT-223-6 package, making it suitable for space-constrained designs. The operating temperature range is -40°C to 125°C. Its low noise and high PSRR characteristics make it well-suited for noise-sensitive analog and RF applications such as wireless communication systems and audio components.
