ADP7182AUJZ-1.8-R7

Overview

The ADP7182AUJZ-1.8-R7 is a CMOS, low dropout (LDO) linear regulator designed for negative voltage regulation. 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 delivers a fixed output voltage of −1.8 V with an initial accuracy of ±1%. It features low noise performance of 18 μV rms and high power supply rejection ratio (PSRR). The regulator is stable with small 2.2 μF ceramic output capacitors and 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
Maintains stability with small ceramic output capacitors
Includes built-in 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 against the manufacturer's ordering guide before procurement. Ensure that the application circuit utilizes the recommended minimum capacitance values to maintain stability. Confirm that the input voltage range and load current requirements fall within the specified operational limits defined in the datasheet specifications.

Selection Notes

Select this component when a negative voltage rail is required for high-performance analog or mixed-signal circuits. Consider the −28 V maximum input voltage capability and the −200 mA output current limit. Evaluate the thermal resistance characteristics relative to the PCB layout and ambient temperature conditions to ensure junction temperature remains within safe operating limits during operation.

Part Context

The ADP7182 series consists of CMOS LDO linear regulators intended for regulating high-performance analog and mixed-signal circuits. The family offers both fixed output voltages and adjustable versions. This specific part represents the fixed −1.8 V output variant housed in a 5-lead TSOT package, providing a compact solution for space-constrained designs requiring negative voltage regulation.
