Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and conditions see the Electrical Characteristics.
Note 2: The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Note 3: Current out of a pin is indicated as a negative value.
Note 4: OUT bias current (disabled) due to leakage current through an internal 0.9 MΩ resistance from SENSE to VOUT.
Note 5: Junction to ambient thermal resistance is highly application and board layout dependent. Specified thermal resistance values for the package specified
is based on a 4-layer, 4"x3", 2/1/1/2 oz. Cu board as per JEDEC standards is used.
Note 6: The GATE pin voltage is typically 7.5V above VIN when the LM25066A is enabled. Therefore the Absolute Maximum Rating for VIN applies only when
the LM25066A is disabled, or for a momentary surge to that voltage since the Absolute Maximum Rating for the GATE pin is also 20V.
Note 7: All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production at T
are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
