Overview
The ADP7158ARDZ-3.0-R7 is a fixed-output linear regulator providing 3.0 V at up to 2 A load current. It operates from an input voltage range of 2.3 V to 5.5 V with a typical dropout voltage of 200 mV at full load. The device features ultralow noise, delivering 0.9 µV rms integrated noise (100 Hz to 100 kHz) and 1.7 nV/√Hz spectral density (10 kHz to 1 MHz). Power supply rejection ratio reaches 70 dB from 1 kHz to 100 kHz. Initial output accuracy is ±0.6%, expanding to ±1.5% over line, load, and temperature variations. Quiescent current is 4.0 mA at no load and 9.0 mA at 2 A, with shutdown current at 0.2 µA.
Feature Summary
- Ultralow noise performance optimized for RF applications
- High power supply rejection ratio across wide frequency bands
- Precision enable pin with programmable logic thresholds
- Stable operation with small ceramic output capacitors
Applications
- Phase-locked loops (PLLs)
- Voltage controlled oscillators (VCOs)
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and thermal characteristics. Confirm that the fixed 3.0 V output matches system requirements as adjustable variants exist within the family. Ensure proper PCB layout and capacitor selection meet minimum ESR and capacitance specifications for stability.
Selection Notes
Select this component when low noise and high PSRR are critical for sensitive RF circuits. Verify input voltage headroom meets the dropout requirements under maximum load conditions. Consider thermal dissipation capabilities based on ambient temperature and board layout constraints.
Part Context
This part belongs to the ADP7158 series of ultralow noise linear regulators designed for radio frequency applications. It shares architectural similarities with the ADP7159 but offers fixed output voltages instead of adjustable options. The series targets communications infrastructure requiring stable, clean power supplies.
Replacement Considerations
ADP7159 provides similar electrical characteristics but features an adjustable output voltage rather than a fixed 3.0 V option.
