TPS79633DCQ Description

Short technical summary and product information.

The Texas Instruments TPS79633DCQ is a 1A low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It features a fixed 3.3V output and a maximum input voltage of 5.5V.

 

Key electrical characteristics include a very low dropout voltage of 0.33V at a 1A load, a high power-supply rejection ratio (PSRR) of 59dB to 42dB across a frequency range of 100Hz to 100kHz, and a quiescent current of 385µA. The device also offers protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

This regulator is housed in a SOT-223-6 surface-mount package. Its ultralow-noise and high PSRR performance make it suitable for RF applications, audio circuits, and portable electronics where signal integrity is critical.

 

The TPS79633DCQ is stable with a small 1µF ceramic capacitor on the output, contributing to its suitability for space-constrained designs.
