TPS78633DCQ Description

Short technical summary and product information.

The Texas Instruments TPS78633DCQ is a 1.5A low-dropout linear voltage regulator designed for applications requiring high performance and low noise. It provides a fixed 3.3V output voltage and features excellent power-supply rejection ratio (PSRR) and transient response.

 

With ultralow noise characteristics (48 µVRMS) and a fast start-up time of 50 µs, this regulator is well-suited for noise-sensitive analog circuits, RF applications like VCOs and receivers, and audio systems. The device operates over a wide temperature range of -40°C to 125°C.

 

The TPS78633DCQ is available in a SOT-223-6 package, requiring surface mount technology. It includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO) for enhanced reliability.

 

Key electrical specifications include a maximum input voltage of 5.5V, a minimum input voltage of 2.7V, and a typical dropout voltage of 390mV at full load. The quiescent current is typically 265µA, reducing power consumption.
