TPS79333DBVRG4Q1 Description

Short technical summary and product information.

The Texas Instruments TPS79333DBVRG4Q1 is a fixed 3.3V, 200mA low-dropout linear voltage regulator designed for applications requiring high performance and low noise. It features an ultralow noise output of 32 μV and a high PSRR of 70 dB at 10 kHz, making it suitable for noise-sensitive circuits.

 

This regulator operates with an input voltage up to 5.5V and has a very low dropout voltage of 0.18V at 200mA. It includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The device has a fast start-up time of 50 μs and a quiescent current of 220 µA typical.

 

The TPS79333DBVRG4Q1 is available in a compact SOT-23-5 package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C, and it is AEC-Q100 qualified for automotive applications.

 

Key specifications include a 3.3V fixed output, 200mA output current, and a 5.5V maximum input voltage. The device is enabled via a control pin and offers excellent load and line transient responses.
