TPS731125MDBVREP

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS731125MDBVREP 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 IN power_in Unregulated input supply; the datasheet gives an input voltage range of 1.7 V to 5.5 V and an absolute maximum VIN range of -0.3 V to 6 V.
2 GND power_in Ground connection for the regulator.
3 EN input Driving EN high turns on the regulator and driving it low puts the regulator into shutdown mode; EN can be connected to IN if not used, and the absolute maximum VEN range is -0.3 V to 6 V.
4 NR/FB passive On the fixed-voltage version (TPS731125) this is NR, where an external capacitor bypasses noise from the internal bandgap to reduce output noise to very low levels; the FB function applies only to the adjustable version.
5 OUT power_out Output of the regulator; the datasheet states there are no output capacitor requirements for stability.
