TPS79328DBVR Description

Short technical summary and product information.

The Texas Instruments TPS79328DBVR is a 200mA low-dropout linear voltage regulator with an enable feature. It provides a fixed 2.8V output voltage and is suitable for RF applications, audio circuits, and portable devices.

 

Key electrical characteristics include a very low dropout voltage of 112mV at 200mA, low noise of 32μVRMS, and high PSRR of 70dB at 10kHz. The device also features fast start-up time of 50μs and protection against over current, over temperature, reverse polarity, and under voltage lockout.

 

This regulator is available in a compact SOT-23-5 package, making it ideal for space-constrained designs. Its stable operation with a 2.2-μF ceramic capacitor on the output simplifies circuit design.
