Overview
The ADM7150ARDZ-3.0-R7 is an ultralow noise, high PSRR RF linear regulator manufactured by Analog Devices Inc. It operates from a 4.5 V to 16 V input range and provides up to 800 mA of output current with a fixed 3.0 V output voltage. The device features a typical quiescent current of 4.3 mA at no load and a low shutdown current of 0.1 µA. Initial voltage accuracy is ±1%, expanding to ±2% over line, load, and temperature conditions. It achieves excellent power supply rejection exceeding 90 dB from 1 kHz to 100 kHz and maintains stability with a 10 µF ceramic output capacitor.
Feature Summary
- Ultralow output noise performance with spectral density of 1.7 nV/√Hz typical from 10 kHz to 1 MHz
- High power supply rejection ratio (PSRR) exceeding 90 dB across a wide frequency range
- Capable of delivering up to 800 mA output current while maintaining stability with small ceramic capacitors
- Integrated thermal overload and short-circuit protection for enhanced reliability
Applications
- RF mixers and phase-locked loops (PLLs)
- Voltage-controlled oscillators (VCOs)
- Cable digital-to-analog converter (DAC) drivers
- Backhaul and microwave links
Procurement Notes
Verify the specific ordering suffix matches the required package type and tape-and-reel quantity. Confirm that the component meets RoHS compliance standards for your region. Ensure the supplier provides valid traceability documentation. Check for any moisture sensitivity level requirements during storage and handling. Validate that the part number corresponds exactly to the 3.0 V fixed output variant.
Selection Notes
Select this regulator when applications require minimal output noise and high PSRR for sensitive RF circuits. Ensure the input voltage remains within the specified 4.5 V to 16 V range under all operating conditions. Verify that the PCB layout supports the necessary thermal dissipation for the chosen package. Confirm compatibility with standard ceramic capacitors for optimal transient response.
Part Context
This component belongs to the ADM7150 series of ultralow noise linear regulators designed specifically for radio frequency applications. The series offers various fixed output voltages between 1.5 V and 5.0 V. It utilizes an advanced proprietary architecture to achieve superior noise and rejection characteristics compared to standard LDOs.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify that any substitute maintains equivalent noise spectral density and PSRR specifications. Ensure the replacement supports the required 800 mA output current capability.
