Overview
The ADM7150ACPZ-5.0-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 voltage range and provides up to 800 mA of output current with a fixed 5.0 V output. The device features a typical quiescent current of 4.3 mA at no load and a low shutdown current of 0.1 µA. It achieves excellent power supply rejection exceeding 90 dB from 1 kHz to 100 kHz at a 400 mA load. The total integrated output noise is 1.0 µV rms from 100 Hz to 100 kHz, with a spectral density of 1.7 nV√Hz typical from 10 kHz to 1 MHz. Dropout voltage is specified at 0.6 V under full load conditions.
Feature Summary
- Ultralow output noise performance optimized for sensitive radio frequency applications
- High power supply rejection ratio maintained across wide frequency ranges
- Stable operation guaranteed with standard ceramic output capacitors
- Low shutdown current consumption for efficient power management
Applications
- RF mixers and phase-locked loops (PLLs)
- Voltage-controlled oscillators (VCOs) and PLLs with integrated VCOs
- Cable digital-to-analog converter (DAC) drivers
- Backhaul and microwave links in communications infrastructure
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm the ACPZ designation corresponds to the LFCSP package variant required for your design. Ensure compatibility with the manufacturer's humidity sensitivity levels during storage and assembly processes. Cross-reference the exact part number against official distributor catalogs to confirm availability status.
Selection Notes
Select this component when designing circuits requiring minimal output noise and high line regulation. The fixed 5.0 V output eliminates external resistor networks, simplifying board layout. Consider the thermal resistance characteristics of the LFCSP package for heat dissipation requirements. Verify that the input voltage remains within the specified operational range to maintain stability.
Part Context
This device belongs to the ADM7150 series of low dropout linear regulators designed for RF applications. It utilizes an advanced proprietary architecture featuring an internal active ripple filter to isolate the low-noise LDO from input noise. The series offers various fixed output voltages and is available in compact surface-mount packages suitable for space-constrained designs.
Replacement Considerations
Consult the official datasheet for compatible adjustable variants like the ADM7151 if programmable output is required. Verify pinout compatibility before substituting with other LDO families. Check thermal performance specifications to ensure equivalent heat dissipation capabilities in the target application.
