• Manufacturer Part Number: sc186ultrt
• Description: 4a Synchronous Step-down Regulator
• Manufacturer: Semtech Corporation

Electrical Characteristics (continued)
Notes:
(1) The “Output Voltage Tolerance” includes output voltage accuracy, voltage drift over temperature and the line regulation.
(2) A negative current means the current flows into the pin and a positive current means the current flows out from the pin.
