Electrical Specifications
Refer to “Block Diagram”and “Typical Application Schematics”. Operating conditions unless otherwise noted:
V IN = 12V, or V CC = 5V ±10%, T A = -40°C to +85°C. Typical are at T A = +25°C. Boldface limits apply over the operating temperature range, -40°C to +85°C

NOTES:
6. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
7. Minimum V IN can operate below 5.5V as long as VCC is greater than 4.5V.
8. Maximum V IN can be higher than 14V voltage stress across the upper and lower do not exceed 15.5V in all conditions.
9. Circuit requires 150ns minimum on time to detect overcurrent condition.
10. Limits established by characterization and are not production tested.
11. PGOOD Rising Delay is measured from the point where V OUT reaches regulation to the point where PGOOD rises. It does not include the external
soft-start time. The PGOOD Rising Delay specification is measured at 500kHz.
