What is TPS7A4700RGWR used for?
The TPS7A4700RGWR is designed for RF transceivers, phase-locked loops (PLLs), and voltage-controlled oscillators (VCOs) where ultra-low noise power rails are critical to system performance. It is also widely used in high-precision instrumentation, medical equipment, and test-and-measurement systems requiring stable, low-ripple supply voltages. Its wide 3-V to 36-V input range makes it suitable for industrial power supplies and automotive sensor modules.

Frequently Asked Questions
What is the output noise of the TPS7A4700RGWR and why does it matter for RF designs?
The TPS7A4700RGWR achieves an ultra-low output noise of 4.17 μVRMS (10 Hz to 100 kHz), making it one of the quietest LDO regulators available. In RF applications such as PLLs and VCOs, power-supply noise directly degrades phase noise and spurious performance, so a low-noise LDO like the TPS7A4700RGWR is essential for meeting stringent RF system specifications.
What is the input voltage range and maximum output current of the TPS7A4700RGWR?
The TPS7A4700RGWR operates from an input voltage of 3 V to 36 V and can supply up to 1 A of continuous output current. The typical dropout voltage is 307 mV at full 1-A load, with a maximum of 450 mV, allowing efficient regulation even with small input-to-output voltage differences.
What package does the TPS7A4700RGWR use and is it RoHS compliant?
The TPS7A4700RGWR comes in a 20-pin QFN (Quad Flat No-Lead, 4 mm × 4 mm) package, designated JESD-30 code S-PQCC-N20. It is fully RoHS compliant (Pbfree Code: Yes, JESD-609 Code: e4), suitable for lead-free manufacturing processes in industrial, communications, and consumer electronics applications.
Can the TPS7A4700RGWR replace other LDO regulators in existing designs?
The TPS7A4700RGWR is pin-compatible with other devices in the TPS7A47xx family and can serve as a drop-in upgrade for designs requiring lower noise. When substituting other LDOs, verify that the input voltage range (3–36 V), output current (1 A), and adjustable output configuration match your circuit requirements. The RGWR suffix indicates tape-and-reel packaging for high-volume production.
