These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply
when operating the device outside of its rated operating conditions.
(2) The maximum allowable power dissipation is a function of the maximum junction temperature, T_J (max), the junction-to-ambient thermal
resistance, θ_J−A, and the ambient temperature, T_A. The maximum allowable power dissipation at any ambient temperature is calculated
using:
Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator
will go into thermal shutdown. See Application Hints for additional information on heatsinking and thermal resistance.
(3) When used in dual-supply systems where the regulator load is returned to a negative supply, the output voltage must be diode-clamped
to ground.
(4) May exceed the input supply voltage.
(5) Human Body Model, 200 pF discharged through 1.5 kΩ.
Electrical Characteristics
Limits in standard typeface are for T_J = 25°C, and limits in boldface type apply over the full operating temperature range.
Unless otherwise specified: C_IN = 4.7 μF, V_IN = V_O(NOM) + 1V, I_L = 1 mA, C_OUT = 10 μF for 5V parts or C_OUT = 22 μF for 3.3V
parts, Feedback pin is tied to V_TAP pin, Output pin is tied to Sense pin, V_S/D = 2V.

(1) All room temperature limits are 100% production tested. All limits at temperature extremes are ensured via correlation using standard
Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level.
(2) Output or reference voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
(3) Output voltage load regulation is measured at constant junction temperature using low duty cycle pulse testing. Two separate tests are
performed, one for the load current range of 100 μA to 1 mA and one for the 1 mA to 500 mA range. Changes in output voltage due to
heating effects are covered by the thermal regulation specification.
