Overview
The ADP7142AUJZ-R7 is a CMOS 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 typical quiescent current of 50 μA at no load and a shutdown current as low as 1.8 μA. It delivers an ultralow output noise of 11 μV rms across all fixed output options. Power supply rejection ratio reaches 88 dB at 10 kHz, 68 dB at 100 kHz, and 50 dB at 1 MHz. The component utilizes a TSOT-23-5 surface-mount package.
Feature Summary
- Ultralow output noise performance independent of the fixed output voltage setting
- High power supply rejection ratio across multiple frequency bands
- Precision enable pin with programmable logic thresholds and hysteresis
- Stability optimized for small ceramic output capacitors
Applications
- Regulation for noise-sensitive analog and mixed-signal circuits
- Powering ADC and DAC circuits
- Supplying precision amplifiers
- Providing control voltage for VCO VTUNE applications
- Automotive electronics systems
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the exact package type and temperature grade. Confirm that the requested revision matches the latest datasheet specifications. Ensure compatibility with required PCB layout guidelines regarding capacitor selection and thermal dissipation. Validate that the component meets necessary environmental standards for the intended deployment environment.
Selection Notes
Select this regulator when high input voltages up to 40 V must be stepped down efficiently. Consider the TSOT-23-5 package for compact designs requiring surface-mount assembly. Evaluate the need for external soft-start capabilities if inrush current limiting is critical. Verify that the application requires the specific adjustable or fixed output voltage configuration available within the series.
Part Context
This component belongs to the ADP7142 family of low dropout regulators designed for high-performance analog applications. The series includes various fixed output voltage options ranging from 1.2 V to 5.0 V, alongside adjustable variants. The architecture supports operation with minimal external capacitance, facilitating space-constrained designs while maintaining stability and transient response characteristics.
Replacement Considerations
Consult the manufacturer's ordering guide for direct functional equivalents within the same product line. Verify pinout compatibility and thermal resistance values before substituting components. Ensure that any alternative part maintains the required input voltage range and output current capabilities.
