The

l denotes the speciﬁcations which apply over the –40°C to 85°C

temperature range, otherwise speciﬁcations are at TA = 25°C, VIN = 12V. Per typical application (front page) conﬁguration.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The LTM4601AE/LTM4601AE-1 are guaranteed to meet

performance speciﬁcations from 0°C to 85°C. Speciﬁcations over the

–40°C to 85°C operating temperature range are assured by design,

characterization and correlation with statistical process controls. The

LTM4601AI/LTM4601AI-1 are guaranteed and tested over the –40°C to

85°C temperature range.

Note 3: Remote sense ampliﬁer recommended for ≤3.3V output.

Note 4: 100% tested at wafer level only.

Note 5: See Output Current Derating curves for different VIN, VOUT and TA.
