QUICK START GUIDE
1. Connect the positive terminals of the load to the VOUT pins and the negative terminals to the
GND pins.
2. Preset the power supply output to 4.75V to 23V and turn it off.
3. Connect the positive terminal of the power supply output to the VIN pin and the negative
terminal to the GND pin
4. Turn on the power supply; the MP2305 will automatically startup.
5. To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 2.5V to turn
on the regulator or less than 0.7V to turn it off.
6. An under voltage lockout (UVLO) function can be implemented by the addition of a resistor
divider (R4 and R5). The EN threshold is 1.3V, so VIN UVLO threshold is:
