(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 Average Outgoing Quality Level (AOQL).

(2)

The ON/OFF inputs must be properly driven to prevent misoperation. For details, see Operation With ON/OFF Control.

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.
