ADP7182AUJZ-2 is a CMOS, low-dropout (LDO) linear regulator by Analog Devices Inc. It operates from a power supply of -2.7V to -28V and can provide a maximum output current of -200mA.

• Low-Dropout Linear Regulation: Suitable for regulating high-performance analog and mixed-signal circuits powered by -27V to -1.2V.
• High Power Supply Rejection and Low Noise: Output noise voltage of 18 μV rms, independent of output voltage.
• Good Transient Response: Achieves excellent line and load transient response performance with a small 2.2 μF ceramic output capacitor.
• Adjustable Output Voltage: Output voltage can be adjusted from -1.22V to -VIN+VDO via external feedback divider.
• Protection Features: Built-in current-limit and thermal overload protection for safe operation.
• Flexible Enable Logic: Can interface with positive or negative logic levels for design flexibility.
• Compact Packaging: Available in 5-lead TSOT and 6/8-lead LFCSP packages for space-constrained applications.

• Noise-sensitive Applications: ADC and DAC circuits, precision amplifiers where low-noise performance is critical.
• Communications and Infrastructure: Power supply for communication system devices.
• Medical and Healthcare: Precision medical testing instruments requiring stable power supply.
• Industrial and Instrumentation: Sensors, controllers, and other industrial devices.
• IF Digital Receiver: Sampling broadband IF signals in communication receivers.
