Overview
The ADM7160AUJZ-2.5-R7 is a fixed-output ultralow noise linear regulator manufactured by Analog Devices Inc., providing a stable 2.5 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 typical dropout voltage of 150 mV at full load. The device achieves ultralow noise performance, measuring 9.5 µV rms from 0.1 Hz to 100 kHz, without requiring external bypass capacitors. It includes integrated current-limit and thermal overload protection circuits, ensuring reliable operation under adverse conditions.
Feature Summary
- Ultralow noise performance independent of the output voltage level
- Low dropout voltage capability for improved efficiency across wide input ranges
- Integrated current-limit and thermal overload protection mechanisms
Applications
- ADC/DAC power supplies
- RF, VCO, and PLL power supplies
- Post dc-to-dc regulation
Procurement Notes
Verify the specific package type (TSOT-23-5) and output voltage accuracy against the official datasheet before procurement. Confirm that the component meets RoHS compliance requirements for your target market. Ensure that the ordering suffix matches the required reel or cut tape packaging format specified in the manufacturer's documentation.
Selection Notes
Select this regulator for applications requiring high precision and minimal noise in space-constrained designs. It is optimized for use with small ceramic capacitors, reducing overall board footprint. Consider the thermal resistance characteristics when designing for high ambient temperatures or significant power dissipation scenarios.
Part Context
This component belongs to the ADM7160 series of ultralow noise linear regulators. The series offers multiple fixed output voltage options ranging from 1.1 V to 3.3 V. It is designed for analog front-end and RF applications where signal integrity is critical. The device utilizes a PMOS pass transistor controlled by an internal error amplifier.
Replacement Considerations
Consult the official datasheet ordering guide for direct pin-compatible alternatives within the same family. Verify electrical specifications such as output voltage tolerance and quiescent current when considering cross-references from other manufacturers.
FAQ
Does the ADM7160 require an external bypass capacitor for noise reduction?
No, the ADM7160 achieves ultralow noise performance without the need for an external bypass capacitor.
What is the function of the EN pin on the ADM7160?
The EN pin enables or disables the output voltage. Driving it high turns on the regulator, while driving it low turns it off. An internal pull-down resistor holds the input low when left open.
