TPS79633QDCQRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS79633-Q1 is a 1A automotive-grade, low-dropout linear voltage regulator designed for high-performance applications. It features a fixed 3.3V output and is AEC-Q100 qualified for automotive environments, operating from -40°C to +125°C.

 

This LDO regulator offers excellent power-supply rejection ratio (PSRR) of 53dB at 10kHz and low output noise of 54µVRMS (legacy chip) or 78µVRMS (new chip), making it suitable for noise-sensitive analog circuits. It provides a very low dropout voltage of 220mV typical at 1A and is stable with a small 1µF ceramic capacitor.

 

The TPS79633QDCQRQ1 comes in a SOT-223-6 package and supports surface mount installation. It includes an enable control feature and protection against over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

With its combination of low noise, high PSRR, and robust protection features, this regulator is ideal for post-regulation and powering sensitive analog loads in automotive systems.
