The ADP7112 is a CMOS, low dropout (LDO) linear regulator that operates from 2.7 V to 20 V and provides up to 200 mA of output current. This high input voltage LDO is ideal for the regulation of high performance analog and mixed signal circuits operating from 20 V down to 1.2 V rails. Using an advanced proprietary architecture, the device provides high power supply rejection, low noise, and achieves excellent line and load transient response with a small 2.2 µF ceramic output capacitor. The ADP7112 regulator output noise is 11 μV rms independent of the output voltage for the fixed options of 5 V or less.
The ADP7112 is available in 16 fixed output voltage options. The following voltages are available from stock: 1.2 V (adjustable), 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Additional voltages available by special order are 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.75 V, 2.8 V, 2.85 V, 3.8 V, 4.2 V, and 4.6 V.
Each fixed output voltage can be adjusted above the initial set point with an external feedback divider. This allows the ADP7112 to provide an output voltage from 1.2 V to VIN − VDO with high PSRR and low noise.
User programmable soft start with an external capacitor is available in the ADP7112. The ADP7112 is available in a 6-ball 1 mm × 1.2mm WLCSP, making it a very compact solution.

Evaluation Kits (4)
The ADP7112CB-EVALZ is an evaluation board used to demonstrate the functionality of the ADP7112 linear regulator.
Simple device measurements, such as line and load regulation, dropout voltage, and ground current, can be demonstrated with just a single voltage source, load resistors, and a voltmeter or an ammeter. For more details about the linear regulators, visit www.analog.com.
Complete specifications for the ADP7112 are available in the ADP7112 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with this user guide when using the evaluation board.
The ADMX1002 is an ultra-low distortion sinewave and high-resolution arbitrary waveform generator. This high-performance module demonstrates a proprietary digital pre-distortion algorithm that reduces signal distortion below levels that can be achieved with high-performance digital-to-analog converters (DAC) and amplifiers alone. Its differential output can be set to common-mode levels often required to test high-performance analog-to-digital converters (ADC), audio codecs, and other audio ICs and systems. With an easy-to-use SPI interface and small-form factor, the ADMX1002 can be easily embedded into test systems, or simply used on the bench for measurement and characterization.

The AD-96TOF1-EBZ is a proven hardware platform for depth perception. When paired with processor board from the 96Boards eco system, it can be used for 3D software and algorithm development. While the software and algorithms are being developed, the hardware design can be leveraged for productization. ADI can suggest 3rd party developers to help customize the platform to meet individual application needs.
Depending on customer preferences and development experience, different 96Boards processor boards can be used for overall system evaluation and custom development. There is also a Raspberry Pi interface available on the Mezzanine board for extra customer flexibility.
This solution offers the ability to be very small and low power while measuring depth at up to 6m distances, good outdoor and indoor performance and VGA resolution.
It can be used for applications like:
- Industrial automation
- SLAM (Simultaneous Localization and Mapping)
- Augmented Reality
- Virtual Reality
- Automotive sensing
Features & Benefits
The ADI ToF system uses a VGA CCD that enables the user to capture a 640x480 depth map of an image, providing up to 4x higher resolution than many other TOF systems on the market. This enables users to detect and measure the distance to smaller and thinner objects that would otherwise be invisible to other ToF systems. More information is included in our ToF technology page.
