Overview
The ADP7118AUJZ-3.3-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 2.7 V to 20 V and provides up to 200 mA of output current. The device features a fixed 3.3 V output with an initial accuracy of ±0.8%. It delivers ultralow output noise of 11 µV rms and high power supply rejection ratios, reaching 88 dB at 10 kHz. The quiescent current is typically 50 µA with no load, dropping to 1.8 µA in shutdown mode. It is housed in a compact 5-lead TSOT package.
Feature Summary
- Ultralow output noise of 11 µV rms independent of the fixed output voltage
- High power supply rejection ratio of 88 dB at 10 kHz for effective noise filtering
- Precision enable pin with programmable thresholds and hysteresis for controlled startup
- Stable operation with small 2.2 µF ceramic output capacitors
Applications
- Regulation for noise-sensitive analog and mixed-signal circuits
- Powering ADC and DAC circuits as well as precision amplifiers
- Providing power for VCO VTUNE control
- Communications and infrastructure systems
- Medical and healthcare equipment
Procurement Notes
Verify the specific suffix -R7 indicates reel packaging when sourcing. Confirm the AUJZ designation corresponds to the 5-lead TSOT package variant. Ensure the component meets AEC-Q100 automotive qualification requirements if applicable to the target environment. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and revision status before procurement.
Selection Notes
Select this component for applications requiring high input voltages up to 20 V with low noise performance. The fixed 3.3 V output eliminates the need for external feedback resistors, simplifying design. Consider the 5-lead TSOT package for space-constrained layouts. Verify that the minimum capacitance requirement of 1.5 µF is met using X5R or X7R dielectric capacitors to ensure stability across temperature ranges.
Part Context
This device belongs to the ADP7118 family of low dropout regulators designed for high-performance analog applications. The series offers various fixed output voltage options ranging from 1.2 V to 5.0 V. It supports adjustable configurations via external dividers while maintaining low noise characteristics. The family includes multiple package options including LFCSP, SOIC, and TSOT to accommodate different thermal and spatial requirements.
Replacement Considerations
Direct substitutes within the same family include other ADP7118 variants with different output voltages or packages. For example, ADP7118AUJZ-5.0-R7 provides a 5.0 V fixed output in the same TSOT package. Adjustments to external components may be necessary when replacing fixed voltage versions with adjustable ones.
