7.5 Electrical Characteristics

Limits apply over operating junction temperature (T_J ) range of –40°C to +150°C, unless otherwise stated. Minimum and Maximum limits⁽¹⁾ are specified through test, design or statistical correlation. Typical values represent the most likely parametric norm at T_J = 25°C, and are provided for reference purposes only. Unless otherwise stated, the following conditions apply: V_IN = 4 V to 36 V.

(1) MIN and MAX limits are 100% production tested at 25°C. Limits over the operating temperature range verified through correlation using
Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).

(2) This is the current used by the device open loop. It does not represent the total input current of the system when in regulation.

(3) The current limit values in this table are tested, open loop, in production. They may differ from those found in a closed loop application.
