TPS79430DCQR Description

Short technical summary and product information.

The Texas Instruments TPS79430DCQR is a 250mA low-dropout (LDO) linear voltage regulator designed for applications requiring stable and clean power. It provides a fixed output voltage of 3V and operates with an input voltage range of 2.7V to 5.5V.

 

Key features include ultralow noise (32 µVrms), high power-supply rejection ratio (PSRR) of up to 65dB at 100Hz, and a fast start-up time of approximately 50 µs. The device exhibits a low dropout voltage of 210mV at a full load of 250mA. It is stable with a small 2.2µF ceramic capacitor on the output.

 

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

 

The TPS79430DCQR is well-suited for noise-sensitive analog circuits, RF applications like VCOs and ADCs, and portable electronics where power efficiency and signal integrity are critical.
