Overview
The ADM7150ACPZ-5.0-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 range and provides a fixed 5.0 V output. The device features a typical quiescent current of 4.3 mA at no load and a shutdown current of 0.1 µA. Output noise is specified at 1.0 µV rms (100 Hz to 100 kHz) with a 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. Dropout voltage is 0.6 V at 800 mA load. Initial voltage accuracy is ±1%, extending to ±2% over line, load, and temperature conditions.
Feature Summary
- Ultralow noise performance optimized for radio frequency applications
- High power supply rejection ratio across wide frequency ranges
- Stable operation with standard ceramic output capacitors
- Low shutdown current consumption for power-sensitive designs
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 R2 against official documentation to confirm reel packaging specifications. Ensure the fixed 5.0 V output variant matches system requirements. Confirm thermal management aligns with the 8-lead LFCSP package characteristics. Validate that input and output capacitor selections meet minimum capacitance and ESR guidelines for stability.
Selection Notes
Select this component when ultralow noise and high PSRR are critical for RF signal integrity. The fixed 5.0 V output eliminates external resistor networks. Verify that the 4.5 V to 16 V input range accommodates the system supply variations. Consider the 800 mA current capability for powering downstream RF stages efficiently.
Part Context
This part belongs to the ADM7150 family of low dropout linear regulators designed for demanding RF environments. The series offers various fixed output voltages between 1.5 V and 5.0 V. It utilizes an advanced proprietary architecture to achieve superior transient response and noise filtering compared to standard LDOs.
Replacement Considerations
Consult the official ordering guide for direct pin-compatible alternatives within the ADM7150 series. Verify electrical parameters match if substituting with other manufacturers' devices.
FAQ
What is the recommended output capacitor type for stability?
The ADM7150 is optimized for use with 10 µF ceramic capacitors, specifically X7R or X5R types, to ensure stability and optimal transient response.
How does the enable pin function?
Driving the EN pin high turns on the regulator, while driving it low turns off the output. For automatic startup, the EN pin can be connected directly to VIN.
