LM3411-3.3 Electrical Characteristics (continued)
Specifications with standard type face are for TJ = 25°C, and those with boldface type apply over full Operating
Temperature Range. Unless otherwise specified, V(IN) = VREG, VOUT = 1.5V.

VSAT = V(IN) − VOUT, when the voltage at the IN pin is forced 100 mV above the nominal regulating voltage (VREG).

Typical numbers are at 25°C and represent the most likely parametric norm.
(2)
Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods. The limits are used to calculate TIs Averaging Outgoing Level (AOQL).
