Checking for live stock

The Texas Instruments TPS7A3301RGWT is a high-performance negative linear-voltage regulator designed for use in precision power supplies, instrumentation, and industrial electronics. With an input voltage range of -3 V to -36 V and an adjustable output range of -1.18 V to -33 V, this regulator delivers up to 1 A of output current. Its ultralow-noise design (≈16 µV RMS) and high power-supply ripple rejection (72 dB at 10 kHz) make it exceptionally well suited for low-noise analogue, audio, RF, and measurement electronics.

Unique Features and Benefits of the Texas Instruments Linear Voltage Regulator

Input range of -3 V to -36 V supports wide negative-rail systems.
Adjustable output from -1.18 V to -33 V enables flexible negative-rail provisioning.
1 A output current capacity fits many precision analog and industrial applications.
Ultralow noise (approx. 16 µV RMS) and high PSRR (~72 dB) support low-disturbance systems.
CMOS-logic-level ENABLE pin for power sequencing and control.
Wide operating temperature of –40 °C to +125 °C for industrial-grade reliability.

Engineered for Precision Negative-Rail Applications

The TPS7A3301RGWT is built to meet demanding noise and stability requirements in sensitive electronics. The adjustable output feature allows designers to generate bespoke negative rails from standard DC/DC converters or battery systems. Its high PSRR and low output noise make it ideal for circuits where disturbance must be minimised, such as in ADC front-ends, audio amplifiers, and RF modules.

Application Potential of the Product

Negative-rail generation for analogue front-ends and signal-chain ICs.
Precision measurement systems.
Audio and RF designs.
Industrial instrumentation and control modules with negative biasing requirements.
Post DC/DC conversion filtering/regulation in mixed-signal systems.
