Key Features
- Ultra-low noise output specifically designed for noise-sensitive analog, RF, and precision ADC supply rails where supply-injected noise directly degrades signal chain performance
- Wide 3 V to 36 V input voltage range with only 0.26 V nominal dropout voltage enabling efficient regulation from a broad set of supply architectures including 5 V, 12 V, and 24 V rails
- Exceptional 0.002 %/V line regulation and adjustable output voltage providing rock-solid supply accuracy for high-precision instrumentation, reference circuits, and communications equipment
Applications
The TPS7A4901DRBT is engineered for noise-critical power supply rails in RF transceivers, precision data converters, test and measurement equipment, and analog sensor front ends where supply noise directly corrupts measurement or signal quality. Its wide input range and low dropout voltage also make it ideal for industrial field instruments, programmable logic controllers, and communication infrastructure that draw from unregulated or loosely regulated bulk power sources ranging from 5 V to 36 V.

Frequently Asked Questions
What input voltage range does the TPS7A4901DRBT support?
The TPS7A4901DRBT accepts input voltages from 3 V to 36 V, offering exceptional flexibility for use across 5 V, 12 V, 24 V, and other common supply rails found in industrial, communications, and instrumentation equipment, all within a single compact regulator solution.
What is the dropout voltage of the TPS7A4901DRBT?
The device achieves a nominal dropout voltage of just 0.26 V (maximum 0.6 V) at 150 mA output current. This low dropout minimizes power dissipation and allows regulation to continue even when the input-output voltage differential is small, improving overall system efficiency.
Why is the TPS7A4901DRBT suitable for noise-sensitive applications?
The TPS7A4901DRBT is specifically optimized for ultra-low output noise, making it ideal for powering RF stages, high-speed ADCs, DACs, PLLs, and precision reference circuits where supply noise couples directly into signal paths and degrades dynamic range, SNR, or phase noise performance.
What is the output current capability and package of the TPS7A4901DRBT?
The TPS7A4901DRBT delivers up to 150 mA of output current and is housed in an 8-pin WSON (Wafer-Scale Outline No-Lead, JESD-30 code S-PDSO-N8) package. The compact thermal pad package provides good heat dissipation and a minimal PCB footprint for density-critical designs.
Is the output voltage of the TPS7A4901DRBT adjustable?
Yes, the TPS7A4901DRBT is fully adjustable via an external resistor divider, allowing designers to set the output voltage precisely for their target rail. With a line regulation of only 0.002 %/V, the output remains highly stable even as the input voltage varies, ensuring accurate supply for precision circuits.
