Electrical Characteristics
Specifications with standard typeface are for T
J
= 25C, and those in bold face type
apply over the full Junction Temperature Range (40C to 125C). Minimum and Maximum limits are guaranteed through test,
design or statistical correlation. Typical values represent the most likely parametric norm at T
J
= 25C and are provided for
reference purposes only. Unless otherwise specified AVIN = PVIN = 5V. (Continued)

Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Range indicates conditions for which the device is
intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. Test Method is per JESD22-AI14.
Note 3:
V
OUT
measured in a non-switching, closed-loop configuration at the SNS pin.
Note 4:
The enable pin is internally pulled up, so the LM2853 is automatically enabled unless an external enable voltage is applied.
