TPS79533DCQR Description

Short technical summary and product information.

The Texas Instruments TPS79533DCQR is a linear, low-dropout (LDO) voltage regulator designed for various power management applications. It provides a stable 3.3V fixed output voltage with a maximum output current of 500mA.

 

Key electrical characteristics include a wide input voltage range from 2.7V to 5.5V, a low dropout voltage of 110mV typical, and low quiescent current of 0.26mA typical. The regulator features ultra-low noise (33µVrms) and high power-supply rejection ratio (PSRR) of 40dB at 100 KHz, making it suitable for noise-sensitive applications.

 

This device is available in a 6-pin SOT-223 package, requiring surface mount installation. It includes enable control and protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS79533DCQR is designed for excellent load and line transient responses and is stable with a minimum load capacitance of 1µF.
