Overview
The ADP7142AUJZ-5.0-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc., housed in a TSOT-23-5 package. It provides a fixed 5.0 V output with a maximum current of 200 mA and operates from an input voltage range of 2.7 V to 40 V. The device features ultralow noise of 11 µV rms, high power supply rejection ratios of 88 dB at 10 kHz, and a typical quiescent current of 50 µA. Initial accuracy is ±0.8%, with line regulation at ±0.01 %/V and load regulation at 0.002 %/mA. Dropout voltage is typically 200 mV at full load.
Feature Summary
- Ultralow output noise of 11 µV rms independent of the fixed output voltage for options up to 5 V
- High power supply rejection ratio reaching 88 dB at 10 kHz under standard operating conditions
- Precision enable pin featuring programmable thresholds and hysteresis for controlled startup and shutdown
- Stable operation guaranteed with small 2.2 µF ceramic output capacitors
Applications
- Regulation for noise-sensitive analog and mixed-signal circuits
- Powering ADC, DAC circuits, and precision amplifiers
- Providing control voltage for VCO VTUNE applications
- Communications and infrastructure equipment
- Medical, healthcare, industrial, and instrumentation systems
Procurement Notes
Verify the specific package type and suffix against official documentation before procurement. Confirm that the component meets AEC-Q100 automotive qualification requirements if intended for such environments. Ensure the ordering information matches the exact manufacturer part number to avoid compatibility issues with evaluation boards or design tools.
Selection Notes
Select this regulator when high input voltages up to 40 V must be stepped down to low-noise rails. The TSOT-23-5 package limits soft-start functionality compared to LFCSP or SOIC variants. Evaluate thermal performance based on PCB layout and ambient temperature, as the junction temperature depends on power dissipation and thermal resistance characteristics of the chosen footprint.
Part Context
This component belongs to the ADP7142 family of low dropout regulators designed for high-performance analog applications. The series offers various fixed output voltages and adjustable configurations across multiple packages including LFCSP, SOIC, and TSOT. It is engineered to support portable equipment and sensitive signal processing stages requiring stable power delivery with minimal ripple and noise interference.
Replacement Considerations
Consult the official datasheet ordering guide for direct equivalents within the ADP7142 series. Verify package compatibility and electrical specifications before substituting with other LDO regulators.
