TPS79401DCQ Description

Short technical summary and product information.

The Texas Instruments TPS79401DCQ is a 250mA low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It offers high power-supply rejection ratio (PSRR) and ultralow noise characteristics, making it suitable for RF electronics and analog circuits.

 

Key electrical specifications include a maximum input voltage of 5.5V and a minimum input voltage of 2.7V. The output voltage is adjustable, with a typical dropout voltage of 155mV at full load. It provides an output current of up to 250mA. The device also features a fast start-up time of 50µs and a typical quiescent current of 170µA.

 

This regulator is stable with a small 2.2µF ceramic capacitor on the output. It is available in a SOT-223-6 package, suitable for surface mounting. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS79401DCQ is ideal for applications requiring clean power, such as portable RF electronics, wireless communication modules, and audio components.
