Overview
The ADP7118WAUJZ-5.0-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It provides a fixed 5.0 V output with a maximum current of 200 mA and operates from an input voltage range of 2.7 V to 20 V. The device features a typical quiescent current of 50 μA and a shutdown current as low as 1.8 μA. It achieves an output noise of 11 μV rms and offers power supply rejection ratios of 88 dB at 10 kHz, 68 dB at 100 kHz, and 50 dB at 1 MHz. The regulator includes precision enable functionality, thermal overload protection, and overcurrent limiting.
Feature Summary
- Provides ultralow output noise of 11 μV rms independent of the fixed output voltage setting.
- Features high power supply rejection ratio (PSRR) reaching 88 dB at 10 kHz for effective ripple suppression.
- Includes programmable precision enable pin with user-adjustable logic thresholds and hysteresis.
- Operates stably with small 2.2 μF ceramic output capacitors while maintaining excellent transient response.
Applications
- Regulation for noise-sensitive analog and mixed-signal circuits
- Powering ADC and DAC circuits along with precision amplifiers
- Providing power for VCO VTUNE control in communications systems
- Industrial instrumentation and medical healthcare equipment
Procurement Notes
Verify that the specific suffix AUJZ corresponds to the TSOT-23-5 package variant when sourcing this component. Confirm AEC-Q100 automotive qualification status if required for your application environment. Ensure the ordering code matches the exact 5.0 V fixed output specification to avoid functional mismatches with adjustable or other voltage variants.
Selection Notes
Select this part when a stable 5.0 V rail is needed from inputs up to 20 V with minimal footprint. The TSOT-23-5 package limits soft-start programming capabilities compared to LFCSP or SOIC options. Verify that the load current does not exceed 200 mA and that the PCB layout supports the required minimum capacitance for stability.
Part Context
This component belongs to the ADP7118 family of high-input-voltage LDO regulators designed for portable and industrial applications. The WAUJZ designation indicates a specific fixed 5.0 V output version packaged in a compact surface-mount format. It serves as a key power management solution for reducing noise in sensitive signal chains within infrastructure and medical devices.
Replacement Considerations
Direct substitutes include other ADP7118 variants such as ADP7118AUJZ-3.3-R7 for different voltage rails. Cross-family replacements require matching input voltage ranges and output current capabilities while verifying package compatibility and thermal performance characteristics.
