Overview
The ADP7156ACPZ-3.0-R7 is a fixed-output linear regulator providing 3.0 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. It includes precision enable logic, thermal shutdown, and under-voltage lockout. The component is housed in a compact 10-lead LFCSP package.
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 output capacitors
Applications
- Phase-locked loops (PLLs)
- Voltage controlled oscillators (VCOs)
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the 3.0 V output variant matches system requirements. Check for automotive qualification if operating in harsh environments. Ensure ESD precautions are followed during handling due to sensitivity.
Selection Notes
Select this part for noise-sensitive RF circuits requiring high PSRR. Verify input voltage headroom meets the minimum dropout requirement. Ensure PCB layout supports the exposed pad for thermal management. Consider the 10 µF minimum output capacitance constraint for stability.
Part Context
This component belongs to the ADP7156 family of low dropout regulators. It shares architectural similarities with the ADM7155 and ADP7158 but offers distinct current and noise specifications. The family targets high-performance analog and RF systems requiring clean power supplies.

FAQ
What is the minimum required output capacitance for stability?
A minimum of 10 µF ceramic capacitor with low ESR is required for stable operation.
How does the enable pin function?
Driving the EN pin high turns on the regulator, while driving it low disables the output. Automatic startup occurs if EN is tied to VIN.
