TPS2103DBVT 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 | Logic enable input, CMOS and TTL compatible, recommended operating range 0 V to 4 V; on the TPS2103 a logic high selects the IN1 (250 mΩ n-channel) path and a logic low selects the IN2 (1.3 Ω p-channel) path. |
| 2 | GND | power_in | Ground reference for all device voltages; all absolute maximum voltage ratings are specified with respect to GND. |
| 3 | IN2 | input | Auxiliary input to the p-channel (1.3 Ω, 100 mA) MOSFET switch; recommended input voltage 2.7 V to 4 V with a 0.22 µF bypass capacitor, and unused INx pins should not be grounded. |
| 4 | OUT | output | Power switch output; absolute maximum output voltage is -0.3 V to 5 V, with continuous output current rated 500 mA from IN1 and 100 mA from IN2 (140 mA absolute maximum). |
| 5 | IN1 | input | Main input to the n-channel (250 mΩ, 500 mA) MOSFET switch; recommended input voltage 2.7 V to 4 V with a 0.22 µF bypass capacitor, and unused INx pins should not be grounded. |
