Note 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 the limits set forth under the operating ratings which specify the intended range of operating conditions.

the junction-to-ambient thermal resistance for the SOT-23 package,

at any ambient temperature for designs using this device can be calculated using the formula:

If power dissipation exceeds the maximum specified above, the internal thermal protection circuitry will protect the device by reducing the output voltage as required

to maintain a safe junction temperature.

Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin.

Note 4: Limits are guaranteed by testing, statistical correlation, or design.

Note 5: Typical values are derived from the mean value of a large quantity of samples tested during characterization and represent the most likely expected value

of the parameter at room temperature.

Note 6: Switch current limit is dependent on duty cycle (see Typical Performance Characteristics).

Note 7: Guaranteed limits are the same for Vin = 3.3V input.
