TPS79133DBV Description

Short technical summary and product information.

The TPS79133DBV from Texas Instruments is an enhanced product, ultralow noise, high PSRR, fast RF, 100-mA low-dropout linear regulator. It is designed for applications requiring clean power, such as RF circuits and VCOs.

 

This regulator operates with an input voltage range of 2.7V to 5.5V and provides a stable 3.3V fixed output voltage. Key electrical characteristics include a typical quiescent current of 0.17 mA, a noise level of 15 µVrms, and a high Power Supply Rejection Ratio (PSRR) of 37 dB at 100 KHz. The dropout voltage is typically 50 mV.

 

The TPS79133DBV is stable with any 1-µF ceramic capacitor and offers excellent load and line transient response. It features an enable pin for power sequencing and control. The device operates across a wide temperature range of -55°C to 125°C, making it suitable for demanding environments.

 

Packaged in a compact 5-pin SOT-23 (DBV) footprint, measuring 8.12 mm², this regulator is ideal for space-constrained designs in defense, aerospace, and medical applications. Its controlled baseline, single assembly/test site, and fabrication site ensure product traceability and reliability.
