ADP7182

-28V, 200mA, Low Noise, Linear Regulator
Manufactured by:

Product Details

The ADP7182 is a CMOS, low dropout (LDO) linear regulator that operates from −2.7 V to −28 V and provides up to −200 mA of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed signal circuits operating from −27 V down to −1.22 V rails. Using an advanced proprietary architecture, it provides high power supply rejection and low noise, and achieves excellent line and load transient response with a small 2.2 μF ceramic output capacitor.

The ADP7182 is available in a fixed output voltage and an adjustable version that allows the output voltage to range from −1.22 V to −VIN + VDO via an external feedback divider.

The ADP7182 regulator output noise is 18 μV rms independent of the output voltage. The enable logic is capable of interfacing with positive or negative logic levels for maximum flexibility.

The ADP7182 is available in an 8-lead LFCSP package for a small, low profile footprint. The 5-lead TSOT package is scheduled for release by the end of 2013.

Product Details

The ADP7182 evaluation board is used to demonstrate the functionality of the ADP7182 series of linear regulators.

Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage source, a voltmeter, an ammeter, and load resistors.

EVAL-AD7175-2 Circuit Diagram

Product Details

The EVAL-AD7175-2SDZ is a fully featured evaluation kit for the AD7175-2. This board operates in stand alone mode or in conjunction with the System Development Platform, EVAL-SDP-CB1Z . When operated with the System Development Platform software is provided enabling the user to perform detailed analysis of the ADC's performance. This software includes the technical note describing the operation and set up of the evaluation board in standalone operation or when operated with the System Development Platform . When operated in standalone mode the ADZS-BRKOUT-EX3 break out board is recommended for access to various control pins.

The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CB1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.

Product Details

The EVAL-AD7172-2SDZ evaluation kit features the AD7172-2, a low power, 24-bit, 31.25 kSPS, Σ-Δ analog-to-digital converter (ADC) with true rail-to-rail buffers, on-board power supply regulation, and an external amplifier section for amplifier evaluation. A 7 V to 9 V ac-to-dc adapter is regulated to 5 V and 3.3 V; this supplies the AD7172-2 and support components. The EVAL-AD7172-2SDZ connects to a USB port via the SDP on the EVAL-SDP-CB1Z controller board.

The EVAL-AD7172-2SDZ evaluation software fully configures the AD7172-2 device functionality via a user accessible register interface and provides dc time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.

Full details about the device are available in the AD7172-2 data sheet, which should be consulted when using the EVAL-AD7172-2SDZ.
