(1)

Minimum and maximum limits are ensured through test, design, or statistical correlation over the junction temperature (TJ) range of

–40°C to 125°C, unless otherwise stated. Typical values represent the most likely parametric norm at TA = 25°C, and are provided for

reference purposes only.

(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 Average Outgoing Quality Level (AOQL).

(3)

Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below the value measured with a

1-V differential.

6.5 Electrical Characteristics

Unless otherwise specified: TJ = 25°C, VIN = VO(NOM) + 1 V, IL = 1 mA, COUT = 1 μF, VON/OFF = 2 V.
