Note 2: Regulation is measured at constant junction temperature, using pulsed ON time. Note 3: Current Limit is measured at constant junction temperature, using pulsed ON time. Note 4: Dropout is measured at constant junction temperature, using pulsed ON time, and the criterion is VOUT inside target value±2%. Note 5: Dropout test is skipped at the condition of VIN<3V. UTC UNISONIC TECHNOLOGIES CO., LTD. 3 QW-R102-005,I UTC UR133/A LINEAR INTEGRATED CIRCUIT TYPICAL APPLICATION CIRCUIT UTC UR133/A APPLICATION INFORMATION A 10µF (or larger) capacitor is recommended between VOUT and GND for stability. The part may oscillate without the capacitor. Any type of capacitor can be used, but not Aluminum electrolytics when operating below -25°C. The capacitance may be increased without limit. A 1µF capacitor (or larger) should be placed between VIN to GND.
