Overview
The ADM7150ACPZ-3.3-R7 is a fixed-output linear regulator providing 3.3 V at up to 800 mA from an input range of 4.5 V to 16 V. It features ultralow noise with 1.0 µV rms integrated output noise (100 Hz to 100 kHz) and high power supply rejection exceeding 90 dB from 1 kHz to 100 kHz. The device operates within a junction temperature range of -40°C to +125°C, includes an enable pin for shutdown control, and utilizes an 8-lead LFCSP package.
Feature Summary
- Ultralow noise architecture delivering less than 1.7 nV/√Hz spectral density
- High power supply rejection ratio exceeding 90 dB across wide frequency ranges
- Optimized stability using standard 10 µF ceramic output capacitors
- Low shutdown current consumption of 0.1 µA when disabled
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 suffix 'R7' indicates reel packaging configuration. Confirm the 'ACPZ' designation corresponds to the 8-lead LFCSP package type. Ensure the '-3.3' identifier matches the required 3.3 V fixed output voltage. Cross-reference the manufacturer part number against official Analog Devices documentation to validate component authenticity and revision status.
Selection Notes
Select this component for applications requiring stable regulation under high load currents up to 800 mA. The fixed 3.3 V output eliminates external resistor networks. Verify that the minimum input voltage requirement of 4.5 V aligns with the system supply. Consider thermal dissipation requirements based on the difference between input voltage and the 3.3 V output level.
Part Context
This device belongs to the ADM7150 family of RF linear regulators designed for noise-sensitive environments. It shares architectural similarities with adjustable variants like the ADM7151 but provides a fixed 3.3 V output. The series targets infrastructure and communications equipment requiring precise voltage regulation with minimal signal interference.
Replacement Considerations
The ADM7151ACPZ-3.3-R7 offers adjustable output capability instead of fixed voltage. The ADM7150ACPZ-5.0-R7 provides a fixed 5.0 V output option. Verify package compatibility and electrical specifications before substituting.
