TPS79418DGNR Description

Short technical summary and product information.

The Texas Instruments TPS79418DGNR is a 250mA low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It features high power-supply rejection ratio (PSRR), ultralow noise, and fast start-up times.

 

This regulator provides a fixed 1.8V output and is stable with a small 2.2µF ceramic capacitor on the output. Key electrical characteristics include a very low dropout voltage of 155mV at full load and a typical quiescent current of 170µA. The device also offers protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

With its high PSRR (60dB at 10kHz) and low noise (32 µVrms for TPS79428 variant), the TPS79418DGNR is suitable for applications with analog components, such as portable RF electronics, wireless LAN, and ADCs. It is available in an 8-pin HVSSOP package.

 

The TPS79418DGNR supports a wide operating temperature range from -40°C to 125°C. Its enable feature allows for standby mode, reducing supply current to less than 1µA. The device is designed for surface mount applications.
