Overview
The ADP7158ACPZ-3.0-R7 is a fixed-output linear regulator from Analog Devices, providing a precise 3.0 V output with a maximum load current of 2 A. It operates within an input voltage range of 2.3 V to 5.5 V and features ultralow noise characteristics, including 0.9 µV rms integrated noise (100 Hz to 100 kHz) and a typical power supply rejection ratio of 70 dB. The device utilizes a 10-lead LFCSP package and incorporates precision enable functionality alongside thermal shutdown protection.
Feature Summary
- Ultralow noise architecture optimized for radio frequency applications
- High power supply rejection ratio across wide frequency ranges
- Precision enable pin with programmable threshold logic
- Stable operation using standard ceramic capacitors
Applications
- Phase-locked loops (PLLs)
- Voltage controlled oscillators (VCOs)
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix configuration against official documentation to confirm the fixed 3.0 V output rating. Ensure that the ordering details match the required package type and tape-and-reel specifications provided by the manufacturer. Cross-reference the component marking with the datasheet to validate authenticity before integration into production designs.
Selection Notes
Select this component when designing circuits requiring high current delivery with minimal noise interference. Evaluate the thermal resistance parameters relative to the expected ambient temperature and PCB layout constraints. Confirm that the input voltage headroom meets the dropout requirements for the intended operating conditions.
Part Context
This part belongs to the ADP7158 family of RF linear regulators designed for demanding analog signal chain applications. It shares architectural similarities with the ADP7156, ADP7157, and ADM7154 series but offers higher current capacity. The device is engineered to support compact form factors while maintaining strict performance standards for sensitive communication infrastructure.

FAQ
How does the BYP capacitor affect the noise performance?
Increasing the value of the bypass capacitor reduces the output noise voltage below 1 kHz, although it may increase the start-up time of the regulator.
What is the function of the VOUT_SENSE pin?
The VOUT_SENSE pin provides remote sensing capability and is internally connected to the output through a resistor to improve regulation accuracy at the load point.
