Overview
The ADM7160ACPZN3.3-R7 is a fixed-output ultralow noise linear regulator manufactured by Analog Devices Inc., providing a stable 3.3 V output with a maximum load current of 200 mA. It operates within an input voltage range of 2.2 V to 5.5 V and features a low dropout voltage of 150 mV at full load. The device achieves high power supply rejection ratio (PSRR) performance, reaching 54 dB at 100 kHz, while maintaining ultralow output noise levels independent of the output voltage. Designed for space-constrained applications, it utilizes a compact 6-lead LFCSP package.
Feature Summary
- Ultralow noise performance achieved without requiring external bypass capacitors
- High power supply rejection ratio (PSRR) across varying frequencies and loads
- Low dropout voltage enabling efficient operation over wide input voltage ranges
- Integrated enable pin with internal pull-down resistor and built-in hysteresis
Applications
- ADC/DAC power supplies
- RF, VCO, and PLL power supplies
- Post dc-to-dc regulation
Procurement Notes
Verify the specific ordering suffix R7 corresponds to the reel packaging configuration required for your assembly process. Confirm that the LFCSP package variant matches your PCB footprint design. Ensure component authenticity through authorized distribution channels to guarantee adherence to specified electrical parameters and thermal characteristics.
Selection Notes
Select this regulator for applications demanding minimal output noise in analog front-end circuits. Verify that the input voltage remains within the 2.2 V to 5.5 V operational range under all conditions. Consider the thermal resistance of the LFCSP package when designing for high ambient temperatures or significant power dissipation scenarios.
Part Context
This component belongs to the ADM7160 family of ultralow noise linear regulators from Analog Devices. The series offers multiple fixed output voltage options ranging from 1.1 V to 3.3 V. It is engineered specifically for noise-sensitive RF and precision analog applications where clean power delivery is critical.
Replacement Considerations
Direct replacements include other ADM7160 variants with different output voltages or packages, such as ADM7160ACPZN2.5-R7 or ADM7160AUJZ-3.3-R7. Cross-family substitution requires careful evaluation of PSRR, noise specifications, and package dimensions.
