Overview
The ADP7142WAUJZ-2.5-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It operates with 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 2.5 V with an initial accuracy of ±0.8%. It exhibits low noise performance, delivering 11 µV rms output noise independent of the fixed output voltage. Power supply rejection ratio (PSRR) reaches 88 dB at 10 kHz. Quiescent current is typically 50 µA with no load, dropping to 1.8 µA in shutdown mode. The regulator is stable with small 2.2 µF ceramic output capacitors and includes precision enable functionality.
Feature Summary
- Provides ultralow output noise of 11 µV rms across all fixed output voltage options
- Delivers high power supply rejection ratio of 88 dB at 10 kHz for sensitive analog circuits
- Features user-programmable soft start capability via external capacitor connection
- Includes precision enable pin with programmable logic thresholds and hysteresis
Applications
- Regulation for noise-sensitive applications such as ADC and DAC circuits
- Power supply for precision amplifiers and VCO VTUNE control
- Communications and infrastructure equipment requiring clean power rails
- Medical and healthcare instrumentation systems
- Industrial and automotive applications
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm package type matches TSOT-5 specifications. Ensure environmental compliance documentation aligns with project requirements. Validate datasheet revision against manufacturing date codes. Check for any specific handling precautions related to electrostatic discharge sensitivity during assembly processes.
Selection Notes
Select this regulator when high input voltages up to 40 V are present alongside low-noise requirements. Consider the TSOT-5 package for space-constrained designs. Evaluate thermal dissipation capabilities based on expected load currents and ambient temperatures. Verify that the required output voltage falls within the supported fixed options or can be adjusted using external dividers without compromising noise performance.
Part Context
This component belongs to the ADP7142 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. Available packages include LFCSP, SOIC, and TSOT configurations. The architecture supports operation from portable equipment powered by single cells to industrial systems requiring higher input voltages.
Replacement Considerations
Direct substitutes within the same family include other ADP7142 variants with different fixed output voltages or package types. Cross-referencing pin compatibility and electrical specifications is essential when considering alternative components from different manufacturers.
