TPS2103DBVT

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

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.
