Features and Benefits

Evaluates the ADPL42010A in an 8-Lead SO Package
Maximum Output Current: 1A
Jumper programs output voltage according to the resistors set for the output voltage options: 1.2V, 1.5V, 1.8V, 2.5V, 3V, 3.3V, and 5V
Jumper turns the regulator on by connecting the SHDN pin to the INPUT pin or connecting the pin to a external supply to turn the regulator on or off
V_IN, V_OUT, and GND Test Points for Regulation and Dropout Voltage Monitoring
Component placeholder for a resistor connected to J2 that can modify the required output voltage of the user when the SENSE/ADJ pin connects to the output through a resistor divider

Product Details

The EVAL-ADPL42010AZ evaluation board evaluates the ADPL42010A, a 20V, 1A low dropout linear regulator that is optimized for fast transient response. Circuits designed with the ADPL42010A are used primarily in voltage-controlled oscillators, RF power supplies, and in larger systems, as local regulators. The ability to tolerate a wide variety of output capacitors makes the ADPL42010A ideal in space- and cost-sensitive systems.
