DESCRIPTION
FEATURES
The EV2000DJ-00A is the evaluation board for
the MP2000DJ. The board operates from a
1.35V to 6.0V input voltage and regulates the
output voltage at 1.2V with 2% accuracy. By
adjusting the resistor divider values, the board
can regulate the output voltage from 0.5V to 5V.
It can also supply up to 150mA of load current.

QUICK START GUIDE
The output voltage of this board is set to 1.2V. The EN pin is connected to ground with a 10kΩ resistor
for automatic startup. You can connect EN to VIN to disable the MP2000.
1. Attach the positive and negative ends of the load to the VOUT and GND pins, respectively.
2. Attach the input voltage (1.35V ≤ VIN ≤ 6V) and input ground to the VIN and GND pins,
respectively.
3. The default resistor values on the board are R1=28.7kΩ and R2=20kΩ. Changing these resistor
values will change the output voltage. Use the following equation to determine resistor values
for different output voltages:

T1 and T2 are test points for accurately measuring the input and output voltages.
