EVQ20056-G-00A Fast Transient Response, Ultra-Small 250mA Linear Regulator EV Board DESCRIPTION FEATURES The EVQ20056-G-00A evaluation board demonstrates the performance of MPQ2005618, a low noise, low dropout and high PSRR linear regulator. It operates from a 2.5V to 5.5V input voltage and the output voltage is preset internally at 1.8V. The EVQ20056-G-00A can supply up to 250mA of load current, and features current limiting, over temperature protection. An internal PMOS pass element is used to allow a low 150μA ground current, making the MPQ20056-G suitable for battery-power devices.

Connect the positive terminal of the load to VOUT pins, and the negative terminal of the load to GND pins. 2. Preset the power supply output to 2.5V <VIN<5.5V and turn off the power supply. 3. Connect the positive terminal of the power supply output to the VIN pin and the negative terminal of the power supply output to the GND pin. 4. To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 1.5V to turn on the regulator or less than 0.4V to turn it off. 5. Turn on the power supply. The EVQ20056-G will automatically start up. 6. The output voltage is fixed 1.8V. NOTICE: The information in this document is subject to change without notice.
