7 Specifications
7.1 Absolute Maximum Ratings
See (1)(3)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Supply voltage | –0.3 | 6 | V | |
| Voltage at output pin | –0.3 | (VDD + 0.5) | V | |
| Output current | –7 | 7 | mA | |
| Input current at any pin(2) | –5 | 5 | mA | |
| Maximum junction temperature (TJMAX) | 150 | °C | ||
| Storage temperature Tstg | –65 | 150 | °C | |
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) When the input voltage (VI) at any pin exceeds power supplies (VI < GND or VI > V), the current at that pin should be limited to 5 mA.
(3) Soldering process must comply with Reflow Temperature Profile specifications. Refer to www.ti.com/packaging.
7.2 ESD Ratings

|---|---|---|---|---|
| LMT87LP in TO-92 package | ||||
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)(3) | ±2500 | V |
| Charged-device model (CDM), per JEDEC specification JESD22-C101(2) | ±1000 | |||
| LMT87DCK in SC70 package | ||||
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per JESD22-A114(3) | ±2500 | V |
| Charged-device model (CDM), per JEDEC specification JESD22-C101(2) | ±1000 | |||
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
(3) The human-body model is a 100-pF capacitor discharged through a 1.5-kΩ resistor into each pin.
7.3 Recommended Operating Conditions

(1) For information on self-heating and thermal response time see section Mounting and Thermal Conductivity.
(2) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report.
(3) The junction to ambient thermal resistance (RθJA) under natural convection is obtained in a simulation on a JEDEC-standard, High-K board as specified in JESD51-7, in an environment described in JESD51-2. Exposed pad packages assume that thermal vias are included in the PCB, per JESD 51-5.
(4) Changes in output due to self-heating can be computed by multiplying the internal dissipation by the thermal resistance.
7.5 Accuracy Characteristics
These limits do not include DC load regulation. These stated accuracy limits are with reference to the values in Table 3.| PARAMETER | CONDITIONS | MIN(1) | TYP | MAX(1) | UNIT |
|---|---|---|---|---|---|
| Temperature accuracy(2) | 70°C to 150°C; VDD = 3.0 V to 5.5 V | –2.7 | ±0.4 | 2.7 | °C |
| 20°C to 40°C; VDD = 2.7 V to 5.5 V | ±0.6 | °C | |||
| 20°C to 40°C; VDD = 3.4 V to 5.5 V | ±0.3 | °C | |||
| 0°C; VDD = 3.0 V to 5.5 V | –2.7 | ±0.6 | 2.7 | °C | |
| 0°C; VDD = 3.6 V to 5.5 V | ±0.3 | °C | |||
| –50°C; VDD = 3.6 V to 5.5 V | –2.7 | ±0.6 | 2.7 | °C | |
| –50°C; VDD = 4.2 V to 5.5 V | ±0.3 | °C |
(1) Limits are specific to TI's AOQL (Average Outgoing Quality Level).
(2) Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Transfer Table at the specified conditions of supply gain setting, voltage, and temperature (expressed in °C). Accuracy limits include line regulation within the specified conditions. Accuracy limits do not include load regulation; they assume no DC load.
7.6 Electrical Characteristics
Unless otherwise noted, these specifications apply for +VDD = 2.7 V to 5.5 V. MIN and MAX limits apply for TA = TJ = TMIN to TMAX ; typical limits apply for TA = TJ = 25°C.| PARAMETER | TEST CONDITIONS | MIN(2) | TYP (1) | MAX (2) | UNIT | ||

(1) Typicals are at TJ = TA = 25°C and represent most likely parametric norm.
(2) Limits are specific to TI's AOQL (Average Outgoing Quality Level).
(3) Source currents are flowing out of the LMT87. Sink currents are flowing into the LMT87.
(4) Line regulation (DC) is calculated by subtracting the output voltage at the highest supply voltage from the output voltage at the lowest supply voltage. The typical DC line regulation specification does not include the output voltage shift discussed in Output Voltage Shift.
(5) Specified by design and characterization.
