# TPS2102DBVR

**Texas Instruments** · Power Distribution Switches · SOT-23-5

TPS2102DBVR from Texas Instruments, in a SOT-23-5. 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 | EN | input | Enable input, CMOS and TTL compatible (VIH 2 V min, VIL 0.8 V max, 0 V to 4 V); on TPS2102 a logic high turns on the IN2-OUT p-channel switch and a logic low turns on the IN1-OUT n-channel switch. |
| 2 | GND | power_in | Ground; all absolute maximum voltages are specified with respect to GND. |
| 3 | IN2 | input | Auxiliary input voltage, drain of the 1.3-Ω p-channel MOSFET, operating range 2.7 V to 4 V, requires a 0.22-µF bypass; unused INx pins should not be grounded. |
| 4 | OUT | output | Power switch output; continuous output current is rated at 500 mA from IN1 and 100 mA from IN2 under recommended operating conditions. |
| 5 | IN1 | input | Main input voltage, drain of the 250-mΩ n-channel MOSFET, operating range 2.7 V to 4 V, requires a 0.22-µF bypass; unused INx pins should not be grounded. |

## CAD (KiCad official)

- Symbol: `TPS2102DBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tps2102dbvr-etched.step` / `tps2102dbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2102dbvr.step` / `tps2102dbvr.glb` are the bare package body.
