ADP7156ARDZ-2.0-R7

Overview

The ADP7156ARDZ-2.0-R7 is a fixed-output linear regulator providing 2.0 V at up to 1.2 A load current. It operates from an input voltage range of 2.3 V to 5.5 V with a typical dropout voltage of 120 mV at full load. The device features ultralow noise, delivering 0.9 µV rms integrated noise (100 Hz to 100 kHz) and 80 dB PSRR from 1 kHz to 100 kHz. Quiescent current is 4.0 mA at no load, rising to 7 mA at maximum output. Initial accuracy is ±0.6% at 25°C, expanding to ±1.5% across line, load, and temperature variations. Shutdown current is 0.2 µA.

Feature Summary

• Ultralow noise architecture optimized for RF applications
• High power supply rejection ratio across wide frequency bands
• Precision enable pin with defined logic thresholds
• Stable operation with standard ceramic 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 temperature grade. Confirm that the ordering code matches the required output voltage option. Check for automotive qualification requirements if applicable to the target system environment.

Selection Notes

Select this component for designs requiring high PSRR and minimal output noise in compact form factors. Ensure input voltage remains within the specified operating range to maintain regulation. Verify thermal dissipation capabilities based on PCB layout and ambient conditions.

Part Context

This part belongs to the ADP7156 family of high PSRR RF linear regulators. It shares architectural similarities with the ADP7157 and ADP7158 series but offers distinct current ratings and noise specifications tailored for sensitive analog and RF circuitry.
