Overview
The ADM7160ACPZN3.3-R2 is an ultralow noise, low dropout linear regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 2.2 V to 5.5 V and provides a fixed output voltage of 3.3 V with a maximum output current of 200 mA. The device features a typical quiescent current of 265 µA at full load and a shutdown current of 0.2 µA. It achieves a power supply rejection ratio (PSRR) of 54 dB at 100 kHz and delivers ultralow noise performance, specified as 9.5 µV rms over the 0.1 Hz to 100 kHz bandwidth. The component is housed in a compact 6-lead LFCSP package.
Feature Summary
- Ultralow noise performance independent of output voltage without requiring external bypass capacitors
- Low dropout voltage capability of 150 mV at a 200 mA load for improved efficiency
- Integrated enable feature with internal pull-down resistor and built-in hysteresis
- Current-limit and thermal overload protection circuits prevent damage under adverse conditions
Applications
- ADC/DAC power supplies
- RF, VCO, and PLL power supplies
- Post dc-to-dc regulation
Procurement Notes
Verify the specific ordering suffix R2 against official documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with X5R or X7R ceramic capacitors meeting minimum capacitance requirements for stable operation. Confirm that the 6-lead LFCSP package dimensions align with target PCB layout constraints.
Selection Notes
Select this regulator for applications requiring high precision and minimal noise in space-constrained designs. The fixed 3.3 V output eliminates the need for external feedback resistors. Verify that the input voltage remains within the 2.2 V to 5.5 V range and that thermal dissipation does not exceed junction temperature limits under worst-case operating conditions.
Part Context
This component belongs to the ADM7160 series of ultralow noise linear regulators. The series offers 16 fixed output voltage options ranging from 1.1 V to 3.3 V. It is available in both 5-lead TSOT and 6-lead LFCSP packages, designed for stable operation with small ceramic capacitors to support high-performance analog and RF front-end applications.
Replacement Considerations
Consult official Analog Devices documentation for confirmed substitute part numbers. Cross-reference pin configurations and electrical specifications before implementation.
