Overview
The ADP7182AUJZ-3.0-R7 is a CMOS, low dropout (LDO) linear regulator manufactured by Analog Devices Inc. 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 a fixed output voltage of −3.0 V with an initial accuracy of ±1%. It delivers low noise performance of 18 μV rms and achieves a power supply rejection ratio (PSRR) of 66 dB at 10 kHz. The regulator includes positive or negative enable logic, current-limit protection, and thermal overload shutdown.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Supports high input voltage ranges down to −28 V
- Features flexible enable logic compatible with positive or negative control signals
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 datasheet before procurement. Confirm that the ordering suffix matches the required lead frame and tape/reel specifications. Ensure compatibility with the intended PCB layout regarding thermal requirements and pin configurations.
Selection Notes
Select this component when designing negative voltage rails for mixed-signal systems requiring low noise and high PSRR. Consider the −200 mA maximum output current and the −185 mV dropout voltage at full load. Evaluate thermal dissipation based on the difference between input and output voltages and the selected package's thermal resistance characteristics.
Part Context
This part belongs to the ADP7182 series of negative LDO regulators designed for high-performance analog and mixed-signal applications. The series offers various fixed output voltages and adjustable versions in TSOT and LFCSP packages. It utilizes an advanced proprietary architecture to ensure excellent line and load transient response with small ceramic capacitors.
Replacement Considerations
Consult the official Analog Devices ordering guide for confirmed substitute part numbers within the ADP7182 family. Verify pinout compatibility and electrical specifications before substituting.
