Overview
The ADP7142WAUJZ-1.8-R7 is a low dropout linear regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 2.7 V to 40 V and provides up to 200 mA of output current. The device features a fixed output voltage of 1.8 V 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 regulator includes precision enable functionality, user-programmable soft start, and thermal shutdown protection.
Feature Summary
- Provides ultralow output noise independent of the fixed output voltage setting
- Features high power supply rejection across a wide frequency spectrum
- Includes programmable precision enable with adjustable hysteresis thresholds
- Supports user-programmable soft start via external capacitor connection
Applications
- Regulation for noise-sensitive analog and mixed-signal circuits
- Powering ADC and DAC circuits as well as precision amplifiers
- Providing control voltage for VCO VTUNE applications
- Communications and infrastructure equipment power supplies
- Medical, healthcare, industrial instrumentation, and automotive systems
Procurement Notes
Verify the specific suffix WAUJZ against official documentation to confirm package type and temperature grade. Confirm that the ordering code matches the required 1.8 V fixed output specification. Ensure compatibility with the TSOT-23-5 package footprint during procurement planning.
Selection Notes
Select this component when a high input voltage up to 40 V is required alongside low noise performance. The device is suitable for portable equipment due to its low quiescent current. Verify that the application requires a fixed 1.8 V rail or can utilize the adjustable mode for higher voltages.
Part Context
This part belongs to the ADP7142 family of CMOS LDO regulators designed for high-performance analog circuits. The series supports various packages including LFCSP, SOIC, and TSOT. It is AEC-Q100 qualified for automotive applications and offers multiple fixed voltage options ranging from 1.2 V to 5.0 V.
Replacement Considerations
Consult the manufacturer's ordering guide for direct pin-compatible alternatives within the ADP7142 series. Verify that any substitute maintains the same 1.8 V output and TSOT-23-5 package configuration.
