TPS79530DCQR Description

Short technical summary and product information.

The Texas Instruments TPS79530DCQR is a low-dropout (LDO) linear voltage regulator with a fixed 3V output and a 500mA current capability. It features ultra-low noise and high power-supply rejection ratio (PSRR), making it suitable for noise-sensitive applications such as portable RF electronics.

 

The regulator operates with a maximum input voltage of 5.5V and has a low dropout voltage of 110mV typical at 500mA. It includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The device is stable with a small 1µF ceramic capacitor on the output and offers excellent load and line transient responses.

 

Packaged in a 6-pin SOT-223 surface-mount package, the TPS79530DCQR operates within a temperature range of -40°C to 125°C. Its control features include an enable pin for power sequencing. The device also exhibits a PSRR of 50dB at 10kHz and low noise levels of 33µVRMS (legacy chip) or 78µVRMS (new chip).

 

This regulator is designed for applications requiring clean power delivery, benefiting from its fast start-up time and stable operation. The SOT-223 package is standard for many surface-mount designs.
