TPS79401DCQR Description

Short technical summary and product information.

The Texas Instruments TPS79401DCQR is a 250mA low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It provides an adjustable output voltage ranging from 1.22V to 5.4V, with a maximum input voltage of 5.5V.

 

Key electrical characteristics include a low dropout voltage of 155mV at full load, ultralow noise of 32µVrms, and a high PSRR of 60dB at 10kHz. The device also features fast start-up time (50μs) and excellent load and line transient response. It is stable with a minimum load capacitance of 2.2μF.

 

This regulator is available in a compact SOT-223-6 surface-mount package. It includes an Enable control feature and protection against over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

Applications benefiting from its low noise and high PSRR include portable RF electronics, wireless LAN, and audio components.
