Overview
The ADP7118WAUJZ-3.3-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It operates within 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 of 88 dB at 10 kHz, 68 dB at 100 kHz, and 50 dB at 1 MHz. The typical quiescent current is 50 µA with no load, and the shutdown current is 1.8 µA at VIN = 5 V. It includes precision enable functionality and is stable with small 2.2 µF ceramic output capacitors.
Feature Summary
- Ultralow output noise of 11 µV rms independent of fixed output voltage
- High power supply rejection ratio reaching 88 dB at 10 kHz
- Precision enable pin with user-programmable thresholds and hysteresis
- Stable operation with small 2.2 µF ceramic output capacitors
Applications
- Regulation for noise-sensitive applications
- ADC and DAC circuits
- Precision amplifiers
- Power for VCO VTUNE control
- Communications and infrastructure systems
Procurement Notes
Verify the specific suffix 'WAUJZ' against official documentation to confirm automotive qualification status and package type. Ensure the ordering code matches the required fixed 3.3 V output configuration. Cross-reference the manufacturer's latest datasheet revision to validate all electrical parameters before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring high input voltages up to 20 V with low noise requirements. The fixed 3.3 V output eliminates external feedback resistors while maintaining high PSRR. Consider the TSOT-23-5 package for space-constrained layouts. Verify that the application load does not exceed the 200 mA maximum rating and that thermal dissipation remains within limits.
Part Context
This part belongs to the ADP7118 family of low noise CMOS LDO regulators from Analog Devices. The series supports input voltages up to 20 V and offers various fixed output options ranging from 1.2 V to 5.0 V. The WAUJZ suffix indicates a specific automotive-grade variant in a TSOT-23-5 package, designed for robust performance in demanding environments.
Replacement Considerations
Direct substitutes include other ADP7118 variants with different output voltages or packages, such as ADP7118AUJZ-3.3-R7. Verify compatibility regarding package dimensions, pinout configurations, and thermal characteristics when considering alternative parts within the same product family.
