ADP7182AUJZ-2 is a CMOS, low - dropout (LDO) linear regulator by ADI

Functions

• Low - Dropout Linear Regulation: ADP7182AUJZ - 2 is a CMOS, low - dropout (LDO) linear regulator. It operates from a power supply of - 2.7 V to - 28 V and can provide a maximum output current of - 200 mA. It is suitable for regulating high - performance analog and mixed - signal circuits powered by - 27 V to - 1.2 V.
• High Power Supply Rejection and Low Noise: Using an advanced proprietary architecture, it has high power supply rejection and low - noise characteristics. The output noise voltage of the regulator is 18 μV rms, which is independent of the output voltage.
• Good Transient Response: With a small 2.2 μF ceramic output capacitor, it can achieve excellent line and load transient response performance.
• Adjustable Output Voltage: It provides fixed - output - voltage options and an adjustable version. Through an external feedback divider, the output voltage can be adjusted from - 1.22 V to - VIN+VDO.
• Current - limit and Thermal Overload Protection: It has built - in current - limit and thermal overload protection functions to ensure the safety and stability of the device operation.
• Flexible Enable Logic: The enable logic can interface with positive or negative logic levels, providing maximum flexibility for circuit design.
• Small - size Package: It is available in 5 - lead TSOT and 6/8 - lead LFCSP packages, which is suitable for thin - and small - size applications.

Applications

• Noise - sensitive Applications: It is widely used in applications that are sensitive to noise, such as analog - to - digital converter (ADC) and digital - to - analog converter (DAC) circuits, and precision amplifiers, where its low - noise performance can ensure the accuracy of signal conversion and amplification.
• Communications and Infrastructure: In the field of communications, it can be used to supply power to related devices to ensure the stable operation of communication systems.
• Medical and Healthcare: It is applicable to medical equipment, such as providing stable power supply for some precision medical testing instruments to ensure the accuracy of test results.
• Industrial and Instrumentation: In industrial control and instrumentation, it can provide reliable power for various sensors, controllers, and other devices to ensure the normal operation of the industrial system.
• IF Digital Receiver: In a communication receiver, the AD9214BRSZ-105 can be used to sample the IF signal. For example, in an intermediate frequency digital receiver with a center frequency of 70 MHz and a 3dB bandwidth of 10.2 MHz, the chip can sample broadband IF signals at a higher rate, minimizing the signal-to-noise ratio deterioration caused by the sampling rate reduction.
