(1)

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).

(2)

Typical numbers are at 25°C and represent the most likely parametric norm.

(3)

Actual test is done using equivalent current sink instead of a resistor load.

(4)

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

6.6 Electrical Characteristics: 5-V Version

Specifications are for TJ = 25°C, VIN = VREG, and VOUT = 1.5 V (unless otherwise noted).
