Overview
The ADM7160ACPZN1.8-R2 is a fixed-output ultralow noise linear regulator providing 1.8 V at up to 200 mA. It operates from an input voltage range of 2.2 V to 5.5 V with a typical dropout voltage of 150 mV at full load. The device features 54 dB PSRR at 100 kHz and ultralow output noise of 9.5 µV rms (0.1 Hz to 100 kHz). Quiescent current is 265 µA, with shutdown current at 0.2 µA. It includes internal current-limit and thermal overload protection.
Feature Summary
- Ultralow noise performance independent of output voltage without requiring external bypass capacitors
- High power supply rejection ratio (PSRR) of 54 dB at 100 kHz for effective ripple suppression
- Low dropout voltage of 150 mV at maximum load to improve efficiency across wide input ranges
- Integrated enable pin with internal pull-down resistor and built-in hysteresis for stable control
Applications
- ADC/DAC power supplies
- RF, VCO, and PLL power supplies
- Post dc-to-dc regulation
Procurement Notes
Verify the specific suffix R2 indicates tape-and-reel packaging when sourcing. Confirm the ACPZN designation corresponds to the 6-lead LFCSP package variant rather than the TSOT option. Ensure the component meets RoHS compliance standards required for your assembly process before finalizing procurement orders.
Selection Notes
Select this regulator for applications requiring minimal noise floor in analog front-ends or RF circuits. The 1.8 V fixed output suits digital logic interfaces directly. Verify that the PCB layout accommodates the 6-lead LFCSP footprint and provides adequate thermal dissipation for the exposed pad under high load conditions.
Part Context
This component belongs to the ADM7160 family of ultralow noise linear regulators manufactured by Analog Devices. The series offers multiple fixed output voltages ranging from 1.1 V to 3.3 V. It is designed specifically for space-constrained applications utilizing small ceramic capacitors while maintaining high performance metrics.

FAQ
Does the ADM7160 require an external capacitor to achieve its specified noise performance?
No, the device achieves ultralow noise performance without the need for a bypass capacitor.
What is the function of the EN pin if left unconnected?
An internal pull-down resistor on the EN input holds the input low, keeping the regulator disabled when the pin is left open.
