TPS79328QDBVRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS79328QDBVRQ1 is an automotive-qualified, ultralow-noise, high-PSRR, fast RF, 200mA low-dropout linear regulator. It is designed for applications requiring stable and clean power.

 

This regulator features a fixed 2.8V output voltage and can supply up to 200mA of current. Key electrical characteristics include a low dropout voltage of 112mV at full load, ultralow output noise of 32µVrms, and high power-supply rejection ratio (PSRR) of 70dB at 100Hz, decreasing to 43dB at 100kHz. It also boasts a fast start-up time of 50µs.

 

The TPS79328QDBVRQ1 is stable with a minimum output capacitance of 2.2µF. It includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The device operates over a temperature range of -40°C to 125°C.

 

Packaged in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package, this regulator is suitable for space-constrained designs. Its features make it ideal for RF applications, VCOs, and Bluetooth devices where noise and power integrity are critical.
