(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(2) When the input voltage (V_I) at any pin exceeds power supplies (V_I < GND or V_I > +V_S), the current at that pin should be limited to 5 mA.
(3) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200 pF
capacitor discharged directly into each pin.

Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(2) Soldering process must comply with Texas Instruments's Reflow Temperature Profile specifications. Refer to www.ti.com/packaging.
(3) Reflow temperature profiles are different for lead-free and non-lead-free packages.
(4) The junction to ambient thermal resistance (θ_JA) is specified without a heat sink in still air.
Electrical Characteristics
Unless otherwise noted, these specifications apply for +V_S = +3.0 V_DC and I _LOAD = 1 μA. Boldface limits apply for T_A = T_J =
T_MIN to T_MAX ; all other limits T_A = T_J = 25°C.

(1) Typicals are at T_J = T_A = 25°C and represent most likely parametric norm.
(2) Limits are ensured to TI's AOQL (Average Outgoing Quality Level).
(3) Accuracy is defined as the error between the output voltage and +6.25 mV/°C times the device's case temperature plus 424 mV, at
specified conditions of voltage, current, and temperature (expressed in °C).
(4) Nonlinearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight line, over the device's
rated temperature range.
(5) Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating
effects can be computed by multiplying the internal dissipation by the thermal resistance.
