Overview
The ADP7118AUJZ-2.5-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc., housed in a TSOT-23-5 package. It provides a fixed output voltage of 2.5 V with a maximum output current of 200 mA. The device operates from an input voltage range of 2.7 V to 20 V and features a typical quiescent current of 50 μA at no load. It delivers an output noise of 11 μVrms and achieves a power supply rejection ratio of 88 dB at 10 kHz. The regulator includes precision enable functionality, thermal shutdown protection, and overcurrent limiting.
Feature Summary
- Provides ultralow output noise of 11 μVrms independent of the fixed output voltage setting.
- Delivers high power supply rejection ratios across multiple frequencies for sensitive analog circuits.
- Maintains stability using small 2.2 μF ceramic output capacitors.
- Features user-programmable soft start capability via external capacitor connection.
Applications
- Powering ADC and DAC circuits requiring low noise regulation
- Supplying precision amplifiers and VCO VTUNE control
- Communications and infrastructure equipment
- Medical and healthcare instrumentation
Procurement Notes
Verify the specific suffix -R7 indicates reel packaging when sourcing. Confirm the AUJZ designation corresponds to the TSOT-23-5 package variant. Ensure compatibility with the required 2.5 V fixed output specification. Check for AEC-Q100 automotive qualification if applicable to the target environment. Validate that the component meets RoHS compliance requirements for the intended assembly process.
Selection Notes
Select this component for applications requiring high input voltages up to 20 V with low noise performance. The TSOT-23-5 package suits space-constrained designs needing surface mount installation. Consider the 2.2 μF minimum capacitance requirement for stability. Evaluate thermal dissipation capabilities based on the junction-to-ambient resistance of the chosen package. Ensure the load current does not exceed the 200 mA maximum rating.
Part Context
This part belongs to the ADP7118 family of low dropout regulators designed for high-performance analog and mixed-signal circuits. The series offers various fixed output voltages ranging from 1.2 V to 5.0 V. It supports adjustable outputs above the initial set point using external feedback dividers. The family is available in LFCSP, SOIC, and TSOT packages to accommodate different thermal and spatial requirements.
Replacement Considerations
Consult the official ordering guide for direct equivalents within the ADP7118 series. Verify pinout compatibility before substituting with other LDO families. Ensure replacement parts meet the same input voltage and current specifications. Confirm that alternative packages maintain similar thermal performance characteristics.
