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 ADP323 adjustable triple LDO can be configured for any output voltage between 0.5 V and 5 V with two resistors for each output.

Applications

  • Mobile phones
  • Digital cameras and audio devices
  • Portable and battery-powered equipment
  • Portable medical devices
  • Post dc-to-dc regulation

ADP323 Evaluation Board

Product Detail

This product has individual evaluations boards as well as the RedyKit&tm;.

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.
