This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under
which operation of the device is specified. Operating Ratings do not imply performance limits. For performance limits and associated test
conditions, see the Electrical Characteristics tables.
(2) All voltages are with respect to the potential at the GND pin.
(3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(1) Thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at T

=150°C (typ.) and disengages
at T

=135°C (typ.).
(2) Absolute Maximum Output Current specified by design. Recommended input voltage range for output currents in excess of 120mA: 3.1V
to 4.4V.
(3) The Human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. MIL-STD-883 3015.7. The machine
model is a 200pF capacitor discharged directly into each pin.

(2) All voltages are with respect to the potential at the GND pin.
(3) Maximum ambient temperature (T
A-MAX
) is dependent on the maximum operating junction temperature (T
J-MAX-OP
= 125ºC), the
maximum power dissipation of the device in the application (P
D-MAX
), and the junction-to ambient thermal resistance of the part/package
in the application (θ
JA
), as given by the following equation: T
A-MAX
= T
J-MAX-OP
- (θ
JA
× P
D-MAX
). Maximum power dissipation of the
LM2750 in a given application can be approximated using the following equation: P
D-MAX
= (V
IN-MAX
× I
IN-MAX
) - (V
OUT
× I
OUT-MAX
) = [V
IN-
MAX
× ((2 × I
OUT-MAX
) + 5mA)] - (V
OUT
× I
OUT-MAX
). In this equation, V
IN-MAX
, I
IN-MAX
, and I
OUT-MAX
are the maximum voltage/current of the
specific application, and not necessarily the maximum rating of the LM2750.The maximum ambient temperature rating of 85ºC is
determined under the following application conditions: θ
JA
= 55ºC/W, P
D-MAX
= 727mW (achieved when V
IN-MAX
= 5.5V and I
OUT-MAX
=
115mA, for example). Maximum ambient temperature must be derated by 1.1ºC for every increase in internal power dissipation of
20mW above 727mW (again assuming that θ
JA
= 55ºC/W in the application). For more information on these topics, see TI's AN-1187
Application Report (SNOA401) and the POWER EFFICIENCY AND POWER DISSIPATION section of this datasheet.
