# LMT88DCKT

**Texas Instruments** · Temperature Sensors · SC-70-5

LMT88DCKT from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | NC (pin 1) must be left floating or grounded, and other signal traces must not be connected to this pin. |
| 2 | GND | power_in | Device substrate and die attach paddle that must connect to the power supply negative terminal, and pin 2 must be grounded for optimum thermal conductivity to the PCB ground plane (the datasheet also states it may be left floating). |
| 3 | VO | output | Temperature sensor analog output, rated from -0.6 V to (V+ + 0.6 V) with an output current maximum of 10 mA, and the device can source 16 µA and sink 1 µA. |
| 4 | V+ | power_in | Positive power supply pin, operating from 2.4 V to 5.5 V with an absolute maximum supply voltage of 6.5 V. |
| 5 | GND | power_in | Device ground pin that must connect to the power supply negative terminal. |

## CAD (KiCad official)

- Symbol: `LMT88DCKT`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `lmt88dckt-etched.step` / `lmt88dckt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmt88dckt.step` / `lmt88dckt.glb` are the bare package body.
