The TPS7A3001DGNR from Texas Instruments is a high-performance negative linear regulator designed for applications requiring a stable -33V output. It supports up to 200mA of load current with a low dropout voltage of 0.6V. Its low quiescent current of 100µA and excellent PSRR make it ideal for noise-sensitive analog circuits. The compact 8-HVSSOP package is suitable for space-constrained designs.
- Ultra-Low Noise Operation: 72dB PSRR at 120Hz effectively filters supply ripple, ensuring clean power for sensitive analog loads.
- Low Quiescent Current: 100µA quiescent current extends battery life in portable applications.
- High Accuracy: Fixed -33V output with tight regulation maintains performance across load and line variations.
- Compact Package: 8-HVSSOP saves board space without compromising thermal performance.
Negative Rail for Precision Op-Amps
Use the TPS7A3001DGNR to generate a clean -33V rail for high-precision operational amplifiers in test and measurement equipment. Its low quiescent current and high PSRR (72dB at 120Hz) minimize noise coupling from the supply.
Biasing for Avalanche Photodiodes (APDs)
In optical receivers, a stable negative bias voltage is critical. This LDO provides a low-noise -33V bias, ensuring consistent APD gain and reducing signal distortion in high-speed communication systems.
Audio Equipment Negative Supply
For high-end audio DACs and preamplifiers, a clean negative supply is essential. The TPS7A3001DGNR delivers a quiet -33V rail, reducing hum and improving the signal-to-noise ratio.
Industrial Sensor Conditioning
In industrial process control, sensors often require bipolar supplies. This regulator provides a stable negative rail for signal conditioning circuits, ensuring accurate readings in harsh environments.
Portable Medical Devices
With a low 100µA quiescent current, this LDO is suitable for battery-powered medical devices that need a negative rail for analog front-ends, extending battery life while maintaining precision.
