Triple, 200 mA, Low Noise, High PSRR Voltage Regulator
The ADP322/ADP323 200 mA triple output LDOs combine high PSRR, low noise, low quiescent current, and low dropout voltage to extend the battery life of portable devices and are ideally suited for wireless applications with demanding performance and board space requirements.
The ADP322/ADP323 PSRR is greater than 60 dB for frequencies as high as 100 kHz while operating with a low headroom voltage. The ADP322/ADP323 offer much lower noise performance than competing LDOs without the need for a noise bypass capacitor.
The ADP322/ADP323 are available in a miniature 16-lead, 3 mm × 3 mm LFCSP package and are stable with tiny 1 μF ±30% ceramic output capacitors, providing the smallest possible board area for a wide variety of portable power needs.
The ADP322 is available in output voltage combinations ranging from 0.8 V to 3.3 V and offers overcurrent and thermal protection to prevent damage in adverse conditions. The APDP323 adjustable triple LDO can be configured for any output voltage between 0.5 V and 5 V with two resistors for each output.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The ADP322CPZ-REDYKIT is available with a triple, fixed LDO evaluation board and a triple, adjustable LDO evaluation board. All surface-mount ADP322 parts are sorted and stored in the kit with the Analog Devices, Inc., part number and fixed output voltage clearly printed on each zip-top bag.
The ADP322/ADP323 evaluation board is used to demonstrate the functionality of the ADP322/ADP323 series of linear regulators. Simple device measurements, such as line and load regulation, dropout voltage, and ground current, can be demonstrated with two voltage supplies, a few voltmeters, current meters, and load resistors.
Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
This will create a template email that will request from us the proper blank evaluation board for that ADI part and your application's power parameters.
Note: Some parts have multiple blank boards for high/low current or for different topologies (Boost, SEPIC, SEPIC-Cuk), while other blank boards support multiple ADI parts. This is why it is important to run the design tool with your parameters before making your email request from the tool.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
