Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the
device is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin. Test method is per JESD-22-114.
Note 3: Junction-to-ambient thermal resistance (θJA) is based on 4 layer board thermal measurements, performed under the conditions and guidelines set forth
in the JEDEC standards JESD51-1 to JESD51-11. θJA varies with PCB copper area, power dissipation, and airflow.
Note 4: Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation using Statistical
Quality Control (SQC) methods. Limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 5: Typical numbers are at 25°C and represent the most likely parametric norm.
Note 6: Shutdown current includes leakage current of the high side PFET.
Note 7: Current limit is built-in, fixed, and not adjustable.
Note 8: Ripple voltage should be measured across COUT on a well-designed PC board using the suggested capacitors.
