TPS79318DBVR Description

Short technical summary and product information.

The Texas Instruments TPS79318DBVR is a 200mA low-dropout linear regulator designed for RF applications and other noise-sensitive circuits. It offers a fixed 1.8V output voltage with a very low dropout voltage of 112mV at full load.

 

Key electrical characteristics include ultralow noise of 32 µVrms and high power-supply rejection ratio (PSRR) of 70 dB at 10 kHz. The regulator has a fast start-up time of 50 µs and is stable with a 2.2-µF ceramic capacitor.

 

This device is available in a 5-pin SOT-23 package, suitable for surface mounting. It includes an enable feature and protection against over current, over temperature, reverse polarity, and under voltage lockout.

 

Applications for the TPS79318DBVR include RF circuits like VCOs and receivers, audio systems, cellular phones, Bluetooth, and wireless LAN devices.
