TPS79318DBVRG4 Description

Short technical summary and product information.

The TPS79318DBVRG4 from Texas Instruments is a 200mA low-dropout linear voltage regulator designed for applications requiring low noise and high power-supply rejection ratio (PSRR).

 

This device features a fixed 1.8V output voltage and can supply up to 200mA of current. It operates with an input voltage range of 2.7V to 5.5V. Key electrical characteristics include a low dropout voltage of 112mV at 200mA, a typical quiescent current of 0.17mA, and an output noise level of 32 µVRMS.

 

The TPS79318DBVRG4 boasts high PSRR, with values of 70dB at 10kHz and 44dB at 100kHz, which is beneficial for RF applications like VCOs, receivers, and ADCs, as well as audio circuits. It is stable with a minimum load capacitance of 2.2µF.

 

Packaged in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package, this regulator is suitable for space-constrained portable devices. It includes an enable pin for control and features over current, over temperature, reverse polarity, and under voltage lockout protection.
