Overview
The ADM7160AUJZ-2.5-R2 is a fixed-output ultralow noise linear regulator providing 2.5 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 low quiescent current of 265 μA and shutdown current of 0.2 μA. Initial output accuracy is ±1%, extending to −2.5%/+1.5% over line, load, and temperature. It includes internal pull-down on the enable pin, current limit, and thermal protection.
Feature Summary
- Ultralow noise performance independent of output voltage without requiring external bypass capacitors
- Low dropout voltage capability for improved efficiency across wide input ranges
- Integrated current-limit and thermal overload protection circuits
- Internal pull-down resistor on the enable input for automatic startup
Applications
- ADC/DAC power supplies
- RF, VCO, and PLL power supplies
- Post dc-to-dc regulation
Procurement Notes
Verify the specific suffix -R2 indicates reel packaging when sourcing. Confirm the AUJZ designation corresponds to the 5-lead TSOT package variant. Ensure the 2.5 V fixed output matches system requirements. Check datasheet specifications for operating temperature limits and capacitor ESR requirements to guarantee stability.
Selection Notes
Select this component for applications requiring stable analog front-end or RF power delivery in space-constrained designs. The device supports small ceramic capacitors, simplifying layout. Verify that the input voltage remains within the 2.2 V to 5.5 V range. Consider thermal dissipation if the voltage differential is high at maximum load currents.
Part Context
This part 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 compact 5-lead TSOT and 6-lead LFCSP packages designed for high-performance, space-limited applications requiring low profile footprints.
Replacement Considerations
Other ADM7160 variants with different output voltages (e.g., 1.8 V, 3.3 V) share identical electrical characteristics and pinouts. Substitution requires matching the required output voltage level while maintaining the same package type and thermal constraints.
