TPS79401DGNR Description

Short technical summary and product information.

The Texas Instruments TPS79401DGNR is a 250mA low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It features high power-supply rejection ratio (PSRR) of 60dB at 10kHz and ultralow noise performance, making it suitable for RF electronics and analog circuits.

 

This regulator provides a low dropout voltage of 155mV typical at full load and a fast start-up time of 50µs. It operates with an input voltage up to 5.5V and includes an enable control feature. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS79401DGNR is available in an 8-pin HVSSOP package and is surface-mount compatible. It requires a small 2.2µF ceramic capacitor on the output for stability. The device is designed for applications requiring clean power delivery, such as portable RF electronics, wireless LAN, and audio components.
