The ADP123-EVALZ is an adjustable output evaluation board that are used to demonstrate the functionality of the ADP123 linear regulators. 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. ADP123 are low quiescent current, low dropout linear regulators. They are designed to operate from an input voltage between 2.3V and 5.5V and to provide up to 300mA of output current. The low 85mV dropout voltage at a 300mA load improves efficiency and allows operation over a wide input voltage range. ADP123 are specifically designed for stable operation with tiny 1μF ceramic input and output capacitors to meet the requirements of high performance, space constrained applications.
