Overview
The ADP7142AUJZ-2.5-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc., housed in a TSOT-23-5 package. It provides a fixed output voltage of 2.5 V with a maximum output current of 200 mA and operates from an input voltage range of 2.7 V to 40 V. The device features a typical quiescent current of 50 μA, a shutdown current of 1.8 μA at 6 V, and an initial accuracy of ±0.8%. It achieves a power supply rejection ratio of 88 dB at 10 kHz and maintains an output noise of 11 μV rms.
Feature Summary
- Provides ultralow output noise independent of the fixed output voltage setting.
- Features high power supply rejection across multiple frequency bands for sensitive analog circuits.
- Includes user-programmable precision enable thresholds with hysteresis to prevent oscillation.
- Operates stably with small ceramic output capacitors, minimizing board space requirements.
Applications
- Regulation for noise-sensitive applications such as ADC and DAC circuits.
- Powering precision amplifiers and providing control voltage for VCO VTUNE.
- Communications and infrastructure equipment requiring stable rail voltages.
- Medical and healthcare instrumentation systems.
- Industrial and automotive electronics operating under varying load conditions.
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm that the AUJZ designation corresponds to the TSOT-23-5 package variant required for your layout. Ensure compatibility with AEC-Q100 standards if deploying in automotive environments. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and revision level before procurement.
Selection Notes
Select this component when a high input voltage up to 40 V is required alongside a low-noise 2.5 V rail. The TSOT-23-5 package suits designs constrained by surface area. Evaluate thermal dissipation capabilities based on the junction-to-ambient resistance for the chosen footprint. Consider the minimum 2.2 μF ceramic capacitor requirement for stability during transient load changes.
Part Context
This regulator belongs to the ADP7142 family, which offers various fixed output voltages ranging from 1.2 V to 5.0 V. The series supports adjustable outputs via external dividers and includes soft-start functionality in LFCSP and SOIC packages. The AUJZ suffix specifically identifies the five-lead TSOT package configuration within this broader product line.
Replacement Considerations
Direct replacements include other ADP7142 variants with different output voltages or packages, such as the ADP7142ARDZ-2.5-R7 in an SOIC-8 package. Verify pinout compatibility and thermal characteristics when substituting packages. Ensure the replacement maintains the required 200 mA current capability and 40 V input rating.
