DESCRIPTION
Only a 1uF ceramic output capacitor can make the device stable over the whole load range. EUP7903 can be externally set either fixed output mode or adjustable output mode. Connect FB pin to GND to select the fixed output mode. Its output is one of pre-set values: 1.25V~5V (50mV per step). Operated in the adjustable mode when the FB pin is connected to an external resistors divider, its output can be adjusted from 1.25V to 5V. Other key features include over-current protection, thermal shutdown. The device is available in the small SOT23-5 package. FEATURES
