TPS79318DBVRQ1

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

TPS79318DBVRQ1 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 Device input; the recommended VIN range is 2.7 V to 5.5 V, and the absolute maximum is -0.3 V to 6 V (old die) or 6.5 V (new die).
2 GND power_in Regulator ground pin; per the layout guidance, connect each ground plane only at this pin.
3 EN input Active-high enable input; the device is enabled above VEN(HI) (1.7 V min for old die, 0.85×VIN for new die) and shut down below VEN(LOW) (0.7 V max for old die, 0.425 V max for new die), and EN can be tied to IN if shutdown is not needed.
4 BYPASS / NC passive Die-dependent: on the old die this pin is the BYPASS node (external capacitor filters the 250 kΩ internal reference resistor, recommended 0.01 µF typ. with 0.1 µF noted in the typical application); on the new die it is not internally connected and should be tied to ground for thermal performance or left floating.
5 OUT power_out Regulated output; requires a stability capacitor to GND of at least 2.2 µF (old die) or a minimum effective 0.47 µF (new die), with COUT range 1 µF to 10 µF (old) and 1 µF to 200 µF (new) recommended.
