Overview
The ADM7150ACPZ-3.3-R2 is an 800 mA ultralow noise, high PSRR RF linear regulator manufactured by Analog Devices Inc. It operates from a 4.5 V to 16 V input voltage range and provides a fixed 3.3 V output. The device features a typical output noise of 1.0 µV rms (100 Hz to 100 kHz) and a noise spectral density of 1.7 nV/√Hz (10 kHz to 1 MHz). Power supply rejection ratio exceeds 90 dB from 1 kHz to 100 kHz at a 400 mA load. It achieves excellent line and load transient response using only a 10 µF ceramic output capacitor.
Feature Summary
- Ultralow noise performance with integrated reference filtering for sensitive RF applications
- High power supply rejection ratio across wide frequency ranges
- Optimized stability with standard 10 µF ceramic output capacitors
- Low shutdown current consumption for power-efficient systems
Applications
- RF mixers and phase-locked loops (PLLs)
- Voltage-controlled oscillators (VCOs)
- Communications and infrastructure equipment
- Cable digital-to-analog converter (DAC) drivers
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix R2 against official documentation to confirm packaging details and reel specifications. Ensure compatibility with required PCB layout guidelines regarding thermal dissipation and capacitor placement. Confirm that the fixed 3.3 V output meets system requirements without needing adjustable variants like the ADM7151.
Selection Notes
Select this component when ultralow noise and high PSRR are critical for RF signal integrity. The fixed 3.3 V output eliminates external resistor networks. Ensure input voltage remains within the 4.5 V to 16 V range. Verify that the 800 mA current capability aligns with peak load demands while maintaining thermal limits in the chosen package.
Part Context
This part belongs to the ADM7150 family of low dropout linear regulators designed for radio frequency applications. It utilizes an advanced proprietary architecture featuring an internal active ripple filter to isolate the output from input noise. The device integrates a P-channel MOSFET pass transistor controlled by an error amplifier comparing the output to a heavily filtered internal reference.
Replacement Considerations
For adjustable output voltage requirements, consider the ADM7151. Other members of the ADM7150 family offer different fixed output voltages such as 1.8 V, 2.8 V, 4.5 V, and 5.0 V.
