DESCRIPTION
The EVQ20056-G-00A evaluation board demonstrates the performance of MPQ20056- 18, 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. ELECTRICAL SPECIFICATIONS Parameter Symbol Value Units Input Voltage VIN 2.5 – 5.5 V Output Voltage VOUT 1.8 V Load Current IOUT 250 mA
FEATURES
Up to 250mA Output Current Low 100mV Dropout at 250mA Fast Transient Response 70dB PSRR at 1kHz 13μVRMS Low Noise Output Fixed output voltage 1.8V Current Limit and Thermal Protection

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.
