ADP7182AUJZ-R7

Overview

The ADP7182AUJZ-R7 is a CMOS low dropout (LDO) linear regulator designed for negative voltage applications. It operates from an input voltage range of −2.7 V to −28 V and provides up to −200 mA of output current. The device features low noise performance with an output noise of 18 μV rms, independent of the output voltage. It offers high power supply rejection ratio (PSRR) of 66 dB at 10 kHz when VOUT is −3 V. The regulator supports both fixed and adjustable output configurations, with the adjustable version allowing output voltages from −1.22 V to −VIN + VDO via an external feedback divider. It includes current-limit and thermal overload protection.

Feature Summary

Provides low noise regulation suitable for sensitive analog circuits
Supports positive or negative enable logic for flexible control
Stable with small ceramic output capacitors
Includes current-limit and thermal overload protection

Applications

Regulation for noise-sensitive applications
Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits
Precision amplifiers
Communications and infrastructure systems
Medical and healthcare equipment

Procurement Notes

Verify the specific package type and output voltage configuration required for your design, as the ADP7182 series is available in multiple packages including TSOT and LFCSP variants. Confirm that the ordering suffix matches the desired pinout and electrical characteristics. Ensure compatibility with your system's negative voltage rail requirements before procurement.

Selection Notes

Select this component for applications requiring negative voltage regulation with low noise and high PSRR. Consider the input voltage range and maximum output current to ensure it meets your load requirements. Evaluate the package options based on space constraints and thermal management needs. Verify that the enable logic polarity aligns with your system's control signals.

Part Context

The ADP7182 is part of Analog Devices' portfolio of low dropout linear regulators. It is specifically designed for high-performance analog and mixed-signal circuits operating from negative rails. The device utilizes an advanced proprietary architecture to achieve excellent line and load transient response while maintaining low noise and high power supply rejection.
