Overview
The ADM7150ACPZ-4.8-R2 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 4.8 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 delivers excellent line regulation of ±0.01 %/V and load regulation of 0.4 %/A. The regulator achieves a dropout voltage of 0.6 V at 800 mA load 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 exceeding 90 dB from 1 kHz to 100 kHz under specified conditions
- Optimized for use with small 10 µF ceramic output capacitors while maintaining stability
- Integrated enable pin allowing precise control over startup and shutdown states
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 R2 against official documentation to confirm packaging details, as datasheets may reference R7 or other variants. Ensure compatibility with required thermal management solutions given the exposed pad design. Confirm component authenticity through authorized channels to guarantee adherence to specified electrical characteristics and reliability standards.
Selection Notes
Select this regulator for applications requiring strict noise suppression and high ripple rejection in RF signal chains. Consider the 4.8 V fixed output constraint and ensure the input voltage remains within the 4.5 V to 16 V operational window. Evaluate thermal dissipation requirements based on the load current and ambient temperature conditions to maintain junction temperatures within safe limits.
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, all sharing similar architectural benefits such as high PSRR and low dropout characteristics. The LFCSP package provides a compact footprint suitable for space-constrained designs.
Replacement Considerations
Consult the official ordering guide for alternative packages or voltage options within the same family. Verify pinout compatibility and thermal resistance values when substituting with other LDO models. Ensure that any replacement meets the specific noise and PSRR requirements of the target RF application.
