LM1117: LM1117IMPX-3.3/NOPB minimum Vin spec

Yunjing Wang1

Part Number: LM1117

Hi team,

May I know the recommend minimum Vin range of LM1117IMPX-3.3/NOPB? We only see the maximum on datasheet. Thank you!

Hello Yunjing,

The minimum input voltage depends on the voltage dropout and the output voltage. The dropout voltage also depends on the load condition.

A recommendation is to follow the line regulation range, which specifies a minimum voltage of 4.75v for a 3.3v output.

Best regards,

Daniel
