(1) Absolute maximum ratings indicate limits beyond which damage to the component may occur. Operating ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical
Characteristics. Specifications do not apply when operating the device outside of its rated operating conditions.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(3) ESD is tested using the human body model which is a 100pF capacitor discharged through a 1.5k resistor into each pin.
(4) At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink values (if a
heatsink is used). The junction-to-ambient thermal resistance (θ_J-A) for the SOT-223 is approximately 125 °C/W for a PC board mounting
with the device soldered down to minimum copper area (less than 0.1 square inch). If one square inch of copper is used as a heat
dissipator for the SOT-223, the θ_J-A drops to approximately 70 °C/W. The θ_J-A values for the WSON package are also dependent on
trace area, copper thickness, and the number of thermal vias used (refer to the TI AN-1187 Application Report and the WSON
MOUNTING section in this datasheet). If power disspation causes the junction temperature to exceed specified limits, the device will go
into thermal shutdown.
(5) If used in a dual-supply system where the regulator load is returned to a negative supply, the output pin must be diode clamped to
ground.
