Подробнее о продукте
The ADP7158CP-3.3EVALZ evaluation board demonstrates the operation and functionality of the ADP7158 ultralow noise, 2 A, fixed output, radio frequency (RF) linear regulator.
Simple device measurements, such as line and load regulation, dropout voltage, and ground current, can be demonstrated using only a single voltage supply, load resistors, and a voltmeter or an ammeter.
Complete specifications for the ADP7158 ultralow noise, 2 A, linear regulator are available in the ADP7158 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with user guide UG-794 when using the evaluation board.
