TPS79633KTTR Description

Short technical summary and product information.

The Texas Instruments TPS79633KTTR is a 1A low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It offers a fixed 3.3V output voltage with a very low dropout voltage of 330mV at 1A.

 

Key electrical characteristics include ultralow noise (typically 54µVRMS for legacy chips, 78µVRMS for new chips) and high power-supply rejection ratio (PSRR) of 53dB at 10kHz. The regulator has a fast start-up time of 50µs and features protection against over current, over temperature, and reverse polarity.

 

This device is stable with a small 1µF ceramic capacitor on the output. It is supplied in a TO-263-6, D²Pak (5 Leads + Tab), TO-263BA package suitable for surface mounting. The operating temperature range is -40°C to 125°C.

 

Applications benefiting from its high PSRR and low noise include RF electronics, audio circuits, and portable devices requiring fast response times.
